Both silicone and TPE have numerous applications in industries like medicine and consumer goods. However, their differences influence performance, longevity, and other valuable characteristics. Understanding the differences helps narrow options based on requirements and maximize project outcomes. In this article, we will study the differences between silicone and TPE, methods of distinguishing them, and their implications if one is used instead of the other in specific scenarios. Let’s uncover the secret behind these materials while exploring their remarkable properties.
What is the Difference Between TPE and Silicone?
Thermoplastic Elastomers (TPE) and silicone possess unique characteristics that make them appropriate for specific applications. TPE is an elastic material prone to stretching like rubber and is as eas ily moldable as plastic. This makes TPE highly preferred when durability and ease of processing are required during manufacturing. Silicone is a synthetic polymer that is flexible, biocompatible, and high temperature resistant, thus used in medical and food grade applications and in machines that operate at high temperatures. The difference between them is that, in terms of raw materials and performance, TPE is thermoplastic and therefore recyclable. At the same time, silicone is more stable under extreme environmental conditions, rendering it non-recyclable through conventional methods.
Understanding TPE Material Properties
Thermoplastic elastomers, or TPEs, are one type of copolymer that integrates rubber properties with flexible polymer shaped like plastic. The most remarkable feature is that these copolymers can undergo repeated melt processing. Structurally, TPEs consist of hard and soft segments within their molecular chains. The soft segments lend flexibility along with elastic recovery, and the complex parts provide the polymer with mechanical strength and dimensional stability.
Key characteristics of TPEs focus on the degree of tensile strength, elongation at break, and hardness, which is measured using inline ‘Shore’ durometer scales.

Environmental Impact of TPE vs Silicone
Understanding the environmental impact of TPE and silicone requires analyzing the material’s sourcing, production methods, recyclability, and disposal at the end of life. Thermoplastic elastomers are often seen as more eco-friendly within the scope of these parameters. This is because TPE can be processed and recycled, making it less wasteful at the end of its life cycle. Furthermore, the energy required to produce TPE is lower than that needed to produce silicone, which undergoes curing and polymerization processes that demand extensive energy during manufacturing.
While silicone is challenging and doesn’t wear out easily, recycling it isn’t easy. Thermoset silicones are not recyclable using conventional methods due to their chemical structure, which prevents re-melting or re-formation. Programs specifically designed for recycling silicone are still limited in availability, but they do exist. On the other hand, TPE is fully recyclable under standard thermoplastic recycling streams, which aids in reducing waste and facilitates the use of materials in a circular fashion within industrial systems.
Silicone production emits more CO2 than TPE due to silica extraction and the over-tapering construction of silicone polymers, which requires lots of energy. However, in some long-term applications, silicone’s longer functional lifespan and better resistance to most environmental factors can compensate for its initial ecological costs.
Ultimately, the decision on TPE or silicone should be made by considering a complete lifecycle assessment that includes the entire scope of the product’s life: production, use, and disposal, to decide which option is more sustainable for particular cases.

It consists of long-chain silicone polymers and reinforcing fillers cured, usually through a platinum-catalyzed addition process. LSR silicones rank highly for their temperature stability from -60°C to 200°C (-76°F to 392°F), good dielectric properties, and biocompatibility.
Improvements in LSR technologies have expanded their scope to precision molding. These components are now made with increased consistency across the parameters of the part performance—the low viscosity of LSR before curing aids in injection molding, especially at mass manufacturing stages. In addition, silicone rubbers are classified as LSRs and are deemed non-toxic, hypoallergenic, and resistant to UV radiation, ozone, and other chemicals. Such properties have made it an essential material for healthcare, automotive, and electronics. These industries greatly benefit from the strength-to-weight ratio with harsh condition durability.
Material Properties of Liquid Silicone Rubber
Liquid silicone rubber (LSR) has remarkable thermal and mechanical properties and versatile applications in different industries. With a formulation, LSR’s tensile strength can be between 4 and 12 MPa, and elongation at break can be up to 700%. These strengths and flexibility are particularly beneficial for dynamic use, such as gaskets and seals.
Thermally, LSR has extreme operational temperature ranges of -50°C to 250°C. Specialized grades even sharpen reliability in high-temperature automotive components or industrial machinery by tolerating greater peaks than typically operational.
