TPU is a kind of polymer material which is polymerized by diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI), macromolecular polyol and low molecular polyol (chain extender). Its molecular structure is composed of rigid blocks obtained by reaction of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with chain extender, and flexible blocks obtained by reaction of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols.

TPU is a mature environmental protection material with excellent properties of high tension, high tension, toughness and aging resistance. At present, TPU has been widely used in medical and health, electronic and electrical appliances, industry and sports, etc. it has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, climate resistance, etc., which are unmatched by other plastic materials. At the same time, it has many advantages, such as high waterproof, moisture permeability, wind resistance, cold resistance, antibacterial, mildew resistance, heat preservation, UV resistance and energy release Excellent function. Because of its superior performance and environmental protection concept, it is increasingly welcomed by people. TPU can be a substitute for PVC. But the advantages of TPU are beyond the reach of PVC. TPU not only has excellent properties of high tension, high tension, toughness and aging resistance, but also is a mature environmental protection material.

According to the molecular structure, TPU can be divided into polyester type (good oil resistance) and polyether type (good water resistance and oil resistance). The relative density is 1.10-1.25, the polyether type is smaller than the polyester type; according to the processing method, it can be divided into injection molding grade, extrusion grade, blow molding grade, etc.
