Molecular formula of TPU: C13H25BrN2O, TPU is a high molecular weight polyol (chain extender) formed by the co-reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI). molecular materials.

Uses: TPU has excellent properties of high tension, high tensile force, toughness and aging resistance, and is a mature environmental protection material. At present, TPU has been widely used in medical and health, electronic appliances, industry and sports, etc. It has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and weather resistance that other plastic materials cannot match. At the same time, it has many excellent functions such as high waterproof and moisture permeability, windproof, cold proof, antibacterial, mildew proof, warmth retention, UV resistance and energy release.

Thermoplastic polyurethane elastomer TPU can be divided into polyester type and polyether type according to molecular structure, and can be divided into injection molding grade, extrusion grade, blow molding grade, etc. according to the processing method.
