Thermoplastic polyurethane elastomer (TPU), with its excellent properties and wide application, has become one of the important thermoplastic elastomer materials, whose molecules are basically linear with little or no chemical crosslinking.
There are many physical crosslinks formed by hydrogen bonds between linear polyurethane molecular chains, which play a strengthening role in their morphology, thus giving many excellent properties, such as high modulus, high strength, excellent wear resistance, chemical resistance, hydrolysis resistance, high and low temperature resistance and mold resistance. These excellent properties make thermoplastic polyurethane widely used in many fields such as footwear, cable, clothing, automobile, medicine and health, pipe, film and sheet.
