In choosing the most appropriate material for your individual needs, knowing the dissimilarities between TPE (Thermoplastic Elastomer) and silicone is a must. Indeed, the materials are quite different and this has led to their extensive usage in varying fields. They can be used in the production of everyday items that we use while they are also relevant in industries that require extreme conditions. So, how can a person decide which one is the best for his/her project? This manual tackles the isolated differences between TPE and silicone in terms of their technicalities and practicality and goes through their durability, flexibility, safety, cost-effectiveness, and performance in different environments. If you are a manufacturer, a designer, or a regular person trying to solve a problem and do so with the right decision-making process, this article will present you with the necessary information to make an ideal choice.
Introduction to TPE and Silicone
What is TPE?
Thermoplastic elastomers (TPE) are a group of copolymers or physical blends that take the positive aspects of rubber and thermoplastics. These substances possess rubber’s resilience and ductility, and still can be melted and reprocessed like any other standard plastic. TPE is the material most defined by this flexibility under stress through deformation and the subsequent recovery to the original shape; this makes it a highly versatile and efficient material for various applications. TPE contains both “soft” and “hard” materials, which enables the possibility to obtain a wide range of physical properties, such as different hardness, tensile strength, and elongation at break. One area where TPE is extensively employed is the car industry among other sectors because of the low price, easy manufacturing, and high durability. Besides, it constitutes a considerable part of the aforementioned applications. The automotive industry, the biggest consumer of TPE, uses it mostly for air ducts, seals, and other elastomeric applications. Anyways besides all this TPE responds to the heat aging test and meets the specifications of various automotive standards as well as customer specifications.
What exactly is Silicone?
Silicone may be seen as a man-made substance composed of siloxane, which is a fraction of silicon and oxygen atoms mixed with this element tipped with carbon and hydrogen. The term silicone has become a household name in the manufacturing industry because of its adaptability. It has the following physical, mechanical, and usage qualities that everybody loves: heat resistant, flexible, chemical-proof, and biocompatible. In these fields, silicone is applied in a very broad scale: medical, electronic, building, and even car production. In the medical field, the material is approved for use in making implants, and adhesive material owing to its chemical stability and low allergic reactivity. Further, it is unfailingly reliable in even the most rigorous conditions, remaining supple and structurally sound within -100°F to 500°F (-73°C to 260°C). Therefore, this amazing material of silicon is anywhere from the best industrial applications to domestic consumer products.
Thermoplastic Elastomers Overview
Thermoplastic elastomers are a kind of thermoplastic polymers that have rubber’s elastic properties but are easy to process like thermoplastics. Thermoplastic elastomers, or TPEs, have a two-phase structure, where one phase is the soft segment or elastomer that is integrally bonded to the hard segment or thermoplastic. This leads to the formation of features like those of rubber, where one segment determines resilience and the other provides processability. Therefore, these materials are unique because of the flexibility, strength, and ease of operation combined. The feasibility of converting TPEs is opposed to that of thermosetting rubbers. It is a great advantage of the former that they are repeatedly melted, reshaped, and solidified without significant loss in their properties and thus are suitable to be used in different manufacturing fields by various processes like injection molding, extrusion, blow molding, etc.
The use of TPEs is present in all of the major industries because of their unique characteristics. TPEs are in use in the car-making industry: this sector’s weather seals, gaskets and interior parts are largely molded from TPE’s quality resistance to abrasion, age, and harsh temperatures. TPE’s unique material is also to be highly preferred in the area of medical tubing, seals, and soft-touch grips for its ability to be sterilized in an autoclave. Moreover, TPEs are suitable for providing a vast variety of resilient elastomers in appliances and consumer electronics through easy bonding with other materials and low-cost processing. Hence, TPE’s capacity to replace traditional styinf combined with low-cost processing and fast prototyping; as a result, it becomes a key material in modern-day engineering and product development.
Comparing TPE and Silicone
Key Differences Between TPE and Silicone
Material Composition: When it comes to material composition, Thermoplastic Elastomers (TPEs) are a polymer combination that includes polymers generally thermoplastics and elastomers, that have a mixture of both elastic and plastic characteristics. In the other corner of the ring, is a synthetic polymer – Silicone that is derived from silica and has in its main structure something very characteristic – the siloxane bonds (Si-O-Si). This difference in the lowest level of composition affects the properties and the application of both materials.
Thermal Resistance: If we talk about thermal resistance, Silicone presents amazing thermal stability and can go from -58°F up to 392°F (-50°C up to 200°C) without almost any loss of quality. However, TPE has to live with a less generous thermal resistance range, normally being at its best in between -40°F and 230°F (-40°C and 110°C). Thus, silicone is the better choice for situations in which temperature changes are extremely high, while TPE is the better option in conditions with moderate temperatures.
Chemical Resistance: Silicone is a very good material when it comes to oils, greases, water, and many of the chemicals which makes it a great choice for medical devices, automotive seals, and food-safe applications. Even though the TPEs have a limited resistance to chemicals, they might possibly get damaged from the aggressive chemicals, which reduces their usage in applications that demand durable and very high resistance towards chemically aggressive environments.
Recyclability and Sustainability: TPE is a very thin and stretchy type of plastic material while being a thermoplastic material at the same time. It can be melted at a certain temperature, changed into the mold, and thus recycled. On the other hand, silicone is a rigid and hard material which, when reacting with a particular catalyst in the production process, creates a covalent network structure that can only be reprocessed or recycled with great difficulty. TPE is the material that is primarily used in the processes that are related to green and sustainable manufacturing and products.
Cost and Manufacturing Efficiency: As a rule of thumb, silicone wires have always been more expensive to produce due to the sophisticated curing procedures and high base material cost. TPE, in contrast, is easier to handle through commonly used thermoplastic methods, such as injection molding, which is why it is a better and cheaper option for large-scale production. This efficiency has made TPE the top choice for consumer goods and high-volume products in general.
Performance Characteristics: TPE vs Silicone
Performance characteristics should be well thought of when TPE and silicone are being compared. There are several factors that need to be looked upon including temperature resistance, elasticity, durability, and chemical compatibility. Silicone displays outstanding thermal stability, and it is able to maintain physical as well as mechanical properties within a broad temperature range (-60°C to 250°C). Hence, it is the number one choice for applications that have to deal with the greatest cold or heat, such as automotive gaskets, medical seals, or food-grade equipment. TPE, on the other hand, only having a range of temperature usually varying from -40°C to 120°C, can still be a good thermal resistant for most of the consumer and general goods applications.
TPE’s elasticity is so high that it can resemble rubber in texture and flexibility, and it is much easier to mold and is lighter in weight. These properties make it perfect for consumer interfaces that are comfortable and have ergonomic designs. Nonetheless, when it comes to compression set resistance, silicone beats TPE because it guarantees the same elasticity for a long time even when there is a lot of physical stress. Besides, silicone is the most resistant one to UV radiation and other weathering factors, making it a science-fiction-like material for some outdoor and industrial applications.
Chemical tolerance is one of the major things that set them apart. Silicone is extremely unreactive and is impervious to a lot of oils, solvents, and acids, which is why it is most often specified for use in medical-grade and food-safe conditions. TPE, on the other hand, even though it has some degree of chemical resistance, may not be able to provide the same level of performance as silicone when subjected to very strong chemicals or situations demanding very pure standards. These differences underline that the choice of the materials needs to be based on the specific performance criteria of the application and the environmental conditions.
Durability and Longevity of Silicone and TPE
Silicone’s exceptional durability is attributed to its natural thermal stability, resistance to ultraviolet (UV) rays, and the fact that it can last a long time in extreme environmental situations without getting significantly damaged. The material’s elastic property will keep it in one piece and performing favorably after the long term, making it a good choice for projects that need endurance. The material also shows remarkable resistance to damage and decomposition because of repeated mechanical stress or the effect of chemicals, this will again promote the products life cycle for the entire duration of their use in industrial and consumer applications.
TPE is known to be a very durable material, it never dies but it works the best in the case of medium environmental demands. It is proven that a TPE product can be used under a continuous load without failure even if it is showing some signs of deterioration. This behavior of TPE when not failing under a given load is up to one year. But in worst conditions, it may deteriorate within 3 to 6 months. It is important to know that there is a saying that TPE will not break with large environmental deformations. Also, the product TPE is used in different sizes and shapes to produce different effects in the final product. TPE is an elastomer, and as such, it remains a versatile material. Specifically, TPE is functionalized with additives that can be customized for the durability of the end product. The differences between the materials are very important for an engineer, as these differences affect not only the functionality of the product but also the durability and the life of the product.
Applications of TPE and Silicone
Common Uses for TPE in Various Industries
Thermoplastic elastomers, commonly known as TPE, find extensive application across different sectors, with their exclusive blend of elasticity, processability, and endurance. The leading edge of its implementation though is the automotive industry, where TPEs are applied for the production of seals, gaskets, and internal car components mainly for their high resistance to wear and good flexibility over a wide temperature range. Besides that, in the world of consumer goods TPEs are indispensable in the making of soft-touch grips, phone cases, and household items, all due to the user’s opportunity of getting a product with desired tactile features and style.
TPE is the main choice for the flexible tubing, syringe plunger seals, and medical device handles in the medical sector. The reason is that it is compatible with living tissue and easy to sterilize. Therefore, it perfectly serves the jobs in the health sector that require the most touchy materials. Also, the window seals, weatherstripping, expansion joints ways are the sectors wherein the TPE is the most significant part of the industry due to its ability to keep its work focused even after long exposure to the surroundings. In all of these uses, TPE is capable of adapting to a certain set of requirements so that it stays relevant to the industry.
Applications of Silicone in Consumer Products
Thermoplastic elastomers (TPE) have proven to be an instrumental commodity in different manufacturing sectors because of their adaptability, endurance, and maneuverability. TPEs find major application in the automobile industry where they are the main raw material for the production of most rubber-like parts, and also, the more expensive and less versatile thermoplastic polyurethanes. For example, the ability of TPEs to retain and change form at different temperatures, combined with their resistance to chafing, makes them the best for a vehicle part that is supposed to be both flexible and tough at the same time.
TPE materials are also very useful in medicine industry. They are often used in making syringe stoppers and other items such as tubes, and medical films goes to that biocompatibility, ability to be sterilized, and the softness that can be customized; these features ensure that the products easily meet the strictest medical requirements.
Talking about the electronics field, TPE is actively being chosen for wire coverings, appliances coverings, and venting installation due to its electrical insulation features and endurance towards environmental conditions. On top of this, it is environment-friendly during recycling and repurposing, which will fall in line with the electronics industry’s new exuberance over green practices.
For the matters of the last topics, that is, products of the consumer goods and athletic sectors, the machines of TPEs are of becoming so that we see them in products from toothbrushes, to sweatpants and to the down to the part of the highest degree of movements in yoga and sports in the form of yoga mats and the outsoles of sports shoes all having the same in common. The products are marked by the soft and velvety texture that also provides a pleasant and long-time user experience. Hence, these TPE applications are the ones that reveal a strong connection between the material used and the technological backing of the procedure of production through the different areas of work.
Choosing Between TPE and Silicone for Specific Uses
Making a decision on the materials to select for a particular application, the significant performance characteristics, application requirements, and cost constraints must be taken into account in the said process specifically for thermoplastic elastomers (TPE) as well as silicone. The thermoplastic nature of TPEs is the very reason why they are very flexible and have excellent processability since the very nature of plastics makes them a material for molding and remolding with ease. That makes them a first-rate choice for mass production setups and other applications that seek recyclable materials, like car parts and household accessories.
On the contrary to TPE, silicon is deemed to have the best thermal stability, resistance against chemicals and biological compatibility. Silicone proves to be a more reliable material in cases where a greater range of temperature (-90°F to 570°F, depending on the formulation) is required unlike most TPEs. It is hence the text-books option for a medical device design, baking mold, and rubber sealing materials used in the industry. And yet, the fact that it is a completely neutral and non-toxic material means that it is the ideal for products that directly come into contact with the consumer such as medical tubing and baby bottle and human nipples.
The costs involved are another big point differentiating the two materials. TPE, that is absolutely right, is more often than not the cheaper option and especially so in the case of life-cycle consumer goods which are short. However, the stability and durability of silicone are so high that even if the material cost is higher it may be justified for some demanding or long-lasting applications. The designers and producers can be sure of making a good informed choice if they have an in-depth study of the heat that should be generated, the environmental conditions and the life of the product in question.
Manufacturing Processes for TPE and Silicone
Understanding the Injection Molding Process for TPE
Injection molding is a very versatile and productive manufacturing process that companies frequently use when they need to create elastic and hard-wearing components. To start the process, melted TPE granules are required, which are then heated to the point where they can be easily processed. The range for the temperatures required is normally quite wide, it all depends on the material mix. When the material is completely melted, it is forced into a preformed mold cavity where it solidifies due to the high pressure and finally comes out of the mold as a product with the shape already defined.
Among the main reasons of TPE injection molding being considered beneficial is the fast method that is possible to be used because of the thermoplastic nature of the material; that is, cooling and solidifying are quick processes. Moreover, the process permits the making of complicated designs since TPE has very good flow properties, and thus, the complex cavities can be filled with high precision. The real thing is that it can be engaged with overmolding, where it is employed together with rigid thermoplastics or other materials for better part functionality.
The quality control dimension in this process is enormous, injected and factors such as injection pressure, mold temperature, and cooling time are some among the things that can affect the final product directly through the performance. The more advanced ones in injection molding equipment as well as in simulation software allow the manufacturers to optimize such parameters and hence to reduce waste and to make sure the part quality is always of the same level. On the contrary, the world of injection molding has seen its share of changes for the better once the TPE injection molding technology, with its efficacy, scalability, and material diversity, was introduced and put to practice for reasons to be discussed in this article.
Silicone Moulding and Forming Techniques
Silicone processing is mainly about the application of highly specialized techniques for the making and forming of molds that will allow the utilization of the unique material properties, e.g., flexibility, thermal stability, and chemical resistance, of the product to be manufactured to the maximum. The three most common molding and forming methods include liquid injection molding (LIM), compression molding, and extrusion.
Liquid injection molding is a very automated process that works with liquid silicone rubber (LSR). The liquid silicone rubber is fed into the system: mixing, forming, and finally curing within a sealed, closed loop. The liquid injection molding (LIM) is a particularly good method for producing fancy parts in health-care and automotive industries.
On the contrary, compression molding is a much simpler and, in this case, a more primitive technique where pre-measured silicone material is placed into a heated mold and compressed to take its final shape. This method makes it very easy to produce larger parts or components with less intricate designs, and still remain a cost-effective option for the production of low volume parts and contaminants.
Extrusion is also a very common process, whereby the uncured silicone is pushed out through a shaped die, creating continuous profiles such as tubes or seals. This technique is mostly used in cases where long, uniform shapes are required with very high dimensional accuracy.
Even more, in the past days, the use of advanced process controls and the production of custom formulations has contributed to the further improvement of these techniques in terms of their effectiveness and applicability. The whole production is supported by modern technologies which include computer-controlled molding equipment and real-time data monitoring to secure high precision achievement, lowered material consumption, and usage according to the very strict industry standards. The progression has demonstrated the significance of silicone in the context of the various industries by the highly adaptable nature of the material to the processing of complex and ever-different manufacturing demands and thus making the material more widespread.
Comparative Analysis of Production Costs
Silicone is a competitive choice in production materials when comparing costs, because of the performance efficiency and cost effectiveness that come from the material in the center. The production of silicone includes the use of processes that have been optimized and the one which are the most advanced in materials science and automation. The use of computer-controlled systems together with these makes it possible to eliminate any kind of waste that would have been made if the same process had been done manually, which will lead to the reduction of raw material costs in the long run. Apart from that, the longevity and capability of silicone as a material will also result in the reduction of maintenance and replacement charges for the particular end-use applications.
Similarly to how thermoplastic is, silicone has a different production cost that may seem high at the beginning because of the complicated designing and specialized machinery required. Nevertheless, the long-lasting nature and the performance over a long period of time in many cases wipe out the high-cost aspects of being the first one to use it. Furthermore, from among the rubber types, silicone is the one with the best thermal and chemical resistance properties, which are important in not having costs for the secondary processing of the materials in well-ventilated environments. As for the areas where the production centres have been already set up, supply chain efficiency is the other main factor, which, besides, is a way to further cut the production runs. In fact, many of the silicone features are not only compatible with high-priced products but also with the cheap ones. Thus, it can be said that the entry of silicone theety in the industrial market was the beginning of the radical changes and opportunities.
Conclusion: Making the Right Choice
Pointers for the Decision Making of TPE vs. Silicone
The distinction of TPE (Thermoplastic Elastomer) and silicone should be based on a thorough knowledge of their performance attributes and utilization peculiarities. An important aspect to take into account is the temperature range each material can tolerate. Silicone reacts better than TPE in this situation, it can handle temperatures of -58°F to over 482°F (-50°C to 250°C), and thus it can be used in high-temperature conditions like in the car and the cooking apparatus environment. On the other hand, TPE is a good choice for middle-temperature environments but it cannot resist very hot conditions.
One more thing to keep in mind is the mechanical characteristics and the flexibility of the materials. Silicone provides outstanding elasticity and durability, particularly in the cases of dynamic or vibrating applications, while TPE features great versatility in terms of hardness levels that can be adjusted and customized for particular product needs. In addition, it is worth mentioning that the exposure to chemicals and the damage by the UV radiation do not affect silicone significantly, so it can be the best choice for outdoors and industrial conditions, but TPE must be protected from the environment with the use of special additives.
When looking at it from a financial aspect, TPE is for the most part an economically feasible and an efficient material to be used in high volume production processes. This is due to its injection molding simplicity and the ease of recycling. On the other hand, silicone, even if it is more costly, the company gains this cost back in its longer life cycle and reduced maintenance needs, particularly in critical-in-use conditions. In them, a highly significant requisite for a decision to be taken between the two materials is the recognition of your project’s main priorities, e.g. being tough, whether under stress, resistant to environmental conditions, or limited by money.
Future Trends in TPE and Silicone Usage
Advancements in the material science field that are targeted at sustainability, performance, and emerging application demands are what mold the paths of the TPE (Thermoplastic Elastomers) and silicone utilization. For TPE, creative thinking has been done on the themes of recycling sympathetically and making plant-based elements part of the recipe in order to make the process less harmful to the ecology. These breakthroughs are in the forefront of the current scenario as the industries are changing to practices that are more environmentally friendly.
In addition to those, the TPE blends are now designed for a narrower set of applications, e.g., to be flexible at low temperatures and to be resistant to some chemicals, in order to serve the automotive, medical, and electronic industries better.
Silicone, on the other hand, is becoming increasingly popular in the domain of high-precision devices and systems with its virtually indestructible nature under extreme conditions, and its complete blocking to the UV rays and acids. The industries like aerospace, medical devices, and power generation are among the sectors leveraging the unique stability features of silicone. Another aspect of the silicone industry that is picking up is the self-healing silicon materials which can go a long way in product life extension and waste reduction. On the other hand, the new manufacturing technologies like 3D printing of silicone are also one of the major reasons for the growth of the silicone market.
The use of both TPE and silicone is so much engrossed in the progressive aspect of the modern and environmental friendly applications that there is no looking back. Their popularity in technical research and advancement of technologies will be the enabling force for their future potential growth. The development of these materials may continue to be parallel to the set-up of global agendas and technological obligations.
Final Thoughts: Deciding on the Best Material
Suppose I’m choosing the best material for a particular purpose. In that case, I’ll be well-informed by various vital powers and the latest technologies. The major of all, the operational elements of the application are what matter since they are the ones to cut the Gordian knot. For example, the characteristics of the material, like thermal stability, durability, and chemical resistance, should be on the same page with the usage situation. In instances when the material is to be operated in harsh environments, like for making automobile parts or medical tools, the material choice comes down to silicone or high-performance Thermoplastic Elastomers as these have been the stalwarts in these industries.
Furthermore, my top concerns are sustainability and the regulations. The sustainability is not the only reason; green manufacturing plays a big role in protecting the environment. This is especially the case with recycled materials, low environmental impact materials and certification standard adherents when the materials gain a greater popularity. An instance would be new bio-based TPE and silicon material developments that are becoming popular quickly as they solve both the sustainability and functional sides of the objective spectrum as well.
The paper guy also pointed out that he will use a mix of very deep research, performance testing, and advice taken from the manufacturers in his materials selection process so that the material may provide both performance and strategic goals at other companies in a simultaneous mode. Although there are other factors like economics, cost, processing, and adapting to the very changing material, they are all considered during the decision making process. By following the latest happening in the world of materials science, I not only want to be one of the stricter decision-making processes in terms of the environmental, but also want the firm to benefit from the high-quality output.

Frequently Asked Questions (FAQs)
What are the main differences between TPE vs silicone rubber when choosing a material?
There is a great distinction between thermoplastic elastomer (TPE) and silicone rubber in their chemistry and performance: TPE stands for a polymer material that looks and behaves just like rubber but has the advantage of being able to be molded like plastic. Silicone, on the other hand, is a synthetic rubber which is called silicone having a different polymer backbone. TPEs are usually more recyclable and have simplified material handling such as extrusion and molding by melting, while silicones in many cases need a curing process and are capable of withstanding higher temperatures with a supreme heat resistant property. In the medical field and for tubing, silicone is often the choice as it is non-toxic, and has high resistance to chemicals, whereas TPEs are widely spread in low-cost and mostly recyclable consumer products. The materials of the two have a broad spectrum when it comes to melting points and temperature ranges so it is up to you to determine your application weights and match these to the material. Please elaborate on whether safety, processing, or the need for high temperature resistance or elasticity are the most important factors when making a decision.
How does the injection molding process compare for silicone parts and TPEs?
Silicone parts’ injection molding typically involves the usage of liquid silicone rubber (LSR) that it cures in the mold and calls for specialized machines, while TPEs are handled with the use of standard thermoplastic injection molding equipment that melts and cures. LSR has great surface finish and biocompatibility, thus it is greatly feasible for medical devices and high-quality silicone products, on the other hand, TPE’s injection molding stands on top in terms of cycle time and recyclability. TPEs come with both thermoplastic and elastomeric properties and this allows for repair or regrind, on the contrary, the silicone parts that are cured cannot be remelted and have different cure steps. The choice of whether to go for tpe or silicone for injection molding depends on the quite possibly immobile tolerance for high temperature, the extent of the chemical resistance, and the production volume. The cost, the tooling, and the post-processing needs (trimming and demolding) also play their role in determining which process is most appropriate.
Are silicone vs TPE materials better for high-temperature and heat-resistant applications?
TPEs are quite good for heat resistance compared to silicone materials and by entering a special “heat stabilizer” in the compound, TPE can be a good choice for general categories like weather sealing or outdoor use but at the cost of convenience. Thus with a higher ceiling for heat, TPE may well be the better polymer in the applications of products subject to temperatures up to plus and beyond. With a higher heat resistance ~150 °C, it is possible to use TPEs that are close to the upper application temperature of silicones but compound differences and heat history have to be considered. As such the application should always be considered when deciding between the two polymers and pre-approval and testing of some possible applications should be carried out. Siloxanes case in point have their biggest market share in such innovative products as the Apple iPod, LG Prada phone, Apple iPhone, condoms, and leads.
Which one is the better material for medical devices and tubing, silicone rubber, or tpes?
Among all, It has been observed liquid silicone rubber, in particular, is the most frequently chosen material for medical devices and tubing as it has good biocompatibility, chemical resistance, and sterilization, which are the reasons silicone products are so widely used in healthcare settings. On the other hand, TPE materials can be made with medically-compliant formulations and are liked for being cheaper and easier to process, though the same materials might not perform as good as silicone for products like long-term implantables and multiple sterilization cycles. Look at the application closely: certain tpes might be used when it is about one-time components, whereas it is usually the case that reuse or implantable parts are some of the places that you would find silicone materials especially prefered. The desired polymer will be identified by the regulations, product safety, and whether the material must be able to resist aggressive chemicals or high temperatures. Sometimes the producers choose the hybrids of silicone and thermoplastics to get the best of both material worlds.
In which ways do TPE and silicone materials differ in terms of durability, elasticity, and original shape retention?
TPE and silicone are two different materials that possess unique qualities. TPEs may be fabricated in a number of different ways to serve as a good option for parts or merchandise due to its property to be shaped in any form by the consumer. On the other hand, silicone is a DLC based material that is much more durable and resistant to the effects of nature; as a result, in many cases, the silicone remains the same irrespective of weather conditions. Rubber and synthetic rubber comparisons show that silicone elastomers generally resist environmental degradation better than many tpes, which can be prone to compression set or softening under prolonged heat. TPEs provide such advantages in recycling and ease of making plastics; on the other hand, they are not expected to show consistency, and silicones, therefore, are always chosen when long life and reliable performance are required. The ultimate life, exploitation environment, and stress conditions are some of the main factors that can guide the polymer selection. In the case of gaskets, piping, or rubber parts that are in contact with chemicals or heat, silicone is the usual first choice in spite of the higher material costs.
How do recyclability and ease of processing compare between plastic-like tpes and silicone parts?
TPEs act like plastic, and they are in most cases recyclable for with regrind and remelt methods which help for sustainability by using more materials and running a high-volume production that feeds on material recovery. Cured silicone parts can’t be remelted, we must resort to distinct recycling methods, nevertheless, the superb property of silicone to prolong the operational life and to be resistant to decomposing may exceed the issue of the end-of-life time very well. In terms of processing advantages of tpe, they can be applied by extrusion, blow molding, and conventional injection molding, but, on the contrary, silicone demands special LSR processing equipment or even curing operations. One should take into account raw material selection in regard to me and end-of-life disposal methods, the kind of fabrication devices one possesses, and whether the product must show, for example, resistance to extreme temperatures, antimicrobial character or medical-grade biocompatibility. In many situations, it is the choice of particular tpe materials or silicone elastomers which will solely determine the final boundaries between recyclability and performance.
