Polyurethane thermoplastic elastomer (TPU) is generally a linear polymer material polymerized by long-chain Polyols (polyether or polyester) with an average relative molecular weight of 600 ~ 4000, chain extenders with a relative molecular weight of 61 ~ 400 and polyisocyanates. The long-chain Polyo

Compared with rubber, elastomer focuses more on the meaning of physics and material science, and its scope is broader. In addition to rubber, elastomers also include many polymer materials with different elastic deformation and diversified crosslinking modes of macromolecular chains. It can be seen
