TPEE (thermoplastic polyester elastomer) is a block copolymer containing polyester hard segment and polyether soft segment. 

The polyether soft segment and the uncrystallized polyester formed the amorphous phase polyester hard segment crystallization to form the crystallization microzone and the function of physical intersection point.

 TPEE has the elasticity of rubber and the strength of engineering plastics; The soft segment gives it elasticity, making it like rubber; The hard section gives it the processing properties to make it like plastic; Compared with rubber, it has better processing performance and longer service life. Compared with engineering materials, it is also characterized by high strength, while flexibility and dynamic mechanical properties are better.
