The full name of TPE is “thermoplastic elastomer”, which is a kind of elastomer that has the elasticity of rubber at room temperature and can be plasticized at high temperatures. The structure of thermoplastic elastomers is characterized by chemical bonds composed of different resin segments and rubber segments, resin segments form physical crosslinking points by virtue of interchain interaction, and rubber segments are highly elastic chain segments, contributing to elasticity. Therefore, the thermoplastic elastomer has the physical and mechanical properties of vulcanized rubber and the processing properties of thermoplastic plastics and is a new polymer material between rubber and resin, often referred to as the third-generation rubber.
