Santoprene™ Thermoplastic Elastomers (TPE) and ethylene propylene diene monomer (EPDM) rubber offer insulation and sealing for outdoor use. They can be made into custom-designed shapes or made from extrusions or sheets from sponges or solid materials. TPE and EPDM have several similar properties, including resistance to saltwater, freshwater and weather conditions, and ozone and sunlight (UV). They also possess excellent processing properties, and they support using adhesives. Pressure-sensitive adhesives (PSA) are used with EP. Hot melt adhesives, such as 3M hot melt tape, are utilized together with TPEs.
Increasingly, Santoprene thermoplastic elastomers have replaced EPDM rubber to create hard-to-create forms subject to certain temperatures and conditions for application. By comparing TPE vs. EPDM in terms of material properties, product designers and engineers can make the right choice. Based on the purpose and the requirements, materials that conform to specific specifications may be required. Recyclability and ease of processing are also factors to be considered. Additionally, it is beneficial to work with an experienced supplier for the rubber manufacturer and the plastic manufacturing services to provide professional advice on the best type of TPE you should consider.
TPE vs. EPDM: Properties and Comparisons
TPEs are mixtures of rubber and plastic that possess thermoplastic and elastomeric characteristics. They’re also known as thermoplastic rubber (TPR) instead. Like a thermoplastic, TPRs soften when heated but harden when cooled. As an elastomer, they expand under pressure, return to their original form as the stress is released. Because there are different classes of Santoprene thermoplastic rubbers, choosing a TPE or TPR also means selecting a specific type.
