The introduction of the ETPU material


Thermoplastic polyurethane elastomer (ETPU) is a kind of elastomer that can be plasticized by heating and dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, oil resistance and good processing performance. ETPU is widely used in national defense, medical treatment, food and other industries.

Thermoplastic polyurethane elastomer(ETPU), with its excellent properties and wide applications, has become one of the important thermoplastic elastomer materials. Its molecules are basically linear without or little chemical crosslinking. There are many physical crosslinks composed of hydrogen bonds between linear polyurethane molecular chains. The hydrogen bonds strengthen its 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 good properties make thermoplastic polyurethane widely used in many fields, such as shoes, cables, clothing, automobiles, medicine and health, pipes, films and sheets. The final products generally do not need vulcanization and crosslinking, which can shorten the reaction cycle and reduce energy consumption. Because it is basically a linear structure polymer, it can be processed with the same technology and equipment as thermoplastic, such as injection molding, extrusion, blow molding, calendering, etc., especially suitable for medium and small-sized parts in mass production. Waste materials can be recycled and reused. Different additives or fillers can be used in production or processing to improve some physical properties and reduce costs.
