Thermoplastic polyurethane elastomer, with its excellent properties and wide application, has

become one of the important thermoplastic elastomer materials, its molecules are basically

linear, there is no or very little chemical crosslinking. There are many hydrogen bonds formed

between the physical crosslinking of linear polyurethane chains, the shape of the hydrogen bond

play the role of reinforcement, thus giving many excellent properties, such as high modulus, high

strength, excellent wear resistance, chemical resistance, hydrolysis resistance and high temperature

and fungus resistance. The good performance of the thermoplastic polyurethane is widely used in

shoes, clothing, cable, automotive, medical, pipe, film and sheet and many other fields. Final products

generally do not need to be vulcanized cross linked, can shorten the reaction cycle, reduce energy

consumption. Because it is basically a linear polymer structure, using technology and equipment with

the same thermoplastic processing, such as injection molding, extrusion, blow molding, calendering,

medium and small size parts particularly suitable for mass production. The waste material can be

recycled and reused, the production or processing can use different additives or fillers to improve

some physical properties and reduce the cost.
