TPE: Thermoplastic Polyurethane Elastomer
TPE (Thermoplastic Polyester Elastomer) is a block copolymer containing polyester hard segments and polyether soft segments.
Wherein the polyether soft segment and the non-crystalline polyester form the amorphous phase, the hard segment of the polyester partially crystallizes to form a crystalline micro-zone, which serves as a physical crosslinking point.
TPE has the elasticity of rubber and the strength of engineering plastic; the soft segment gives it elasticity so that it behaves like rubber; the hard segment gives it processability making it like plastic; and it has better processability and longer Life; compared with the engineering materials, the same high strength characteristics, and flexibility and dynamic mechanical properties better.
