TPR (Thermoplastic Rubber)

Thermoplastic elastomers (TPE) are a combination of polymers — usually a plastic and a rubber — which consist of both thermoplastic and elastomeric properties, resulting in a product that is extremely easy to use in manufacturing a variety of products. TPEs require little or no compounding and no need to add reinforcing agents, stabilizers, or cure systems.
