Heat-shrinkable elastomer

Thermoplastic elastomers (TPEs), sometimes also called thermoplastic rubbers, are a class of copolymers or physical mixtures of polymers (usually plastics and rubbers) that consist of materials with both thermoplastic and elastomeric properties. Although most elastomers are thermosets, in contrast, thermoplastics are relatively easy to use in manufacturing, for example by injection molding. Thermoplastic elastomers show the typical advantages of both rubber materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongation and return to close to the original shape, resulting in a longer life and better physical range than other materials. The main difference between thermoset elastomers and thermoplastic elastomers is the type of crosslink in their structure. Indeed, crosslinking is a key structural factor that imparts high elasticity.
