What is the composition of the TPU material?
TPU is short for Thermoplastic Urethane, Chinese named thermoplastic polyurethane elastomer, TPU is a polymeric material that is polymerized by the combination of diphthathane dihesionis (MDI), toluene dicycyate (TDI) and macromolecule polyols and amphicos. Its molecular structure is composed of rigid inlay segments of dibenzene methane dicycyate (MDI), toluene dicycyate (TDI) and expansion agent reaction, as well as flexible segments of dibenzene mesothane (MDI), toluene diheocynate (TDI) and macromolecule polyol reactions. TPU is a mature and environmentally friendly material with excellent high tension, high pull force, toughness and anti-aging properties. At present, TPU has been widely used with medical and health, electrical and electronic appliances, industry and sports, which has other plastic materials can not be compared with high strength, toughness, wear resistance, cold resistance, oil resistance, water resistance, aging, climate resistance and other characteristics, at the same time he has high waterproof permeability, wind, cold, antibacterial, mold-proof, warm, Many excellent functions such as UV resistance and energy release.
Thermoplastic polyurethane elastomer TPU can be divided into polyester type and polyether type according to molecular structure, according to the processing method can be divided into injection molding grade, extrusion stage, blow molding grade and so on.
