  TPU is the abbreviation of "Thermoplastic Urethane". Its Chinese name is thermoplastic polyurethane elastomer. TPU is made by diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyol and chain extender. Polymer Materials. Its molecular structure is a rigid block obtained by the reaction of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and a chain extender, as well as diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and macromolecules. The flexible segments obtained by the polyol reaction are alternately constructed. TPU has excellent high tension, high tensile strength, toughness and aging resistance. It is a mature environmentally friendly material. TPU is an environmentally friendly polymer. The Chinese name is thermoplastic polyurethane, also known as waterproof and moisture-permeable membrane. It is a major breakthrough in the application of new environmentally friendly materials for waterproof and breathable fabrics. It overcomes many defects of PVC and PU leather. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, so it is also called the material of the future. TPU film is a film made of TPU pellets through a special process. It inherits the excellent physical properties of TPU and has a wide range of applications. TPU has been widely used in medical and health, electronic appliances, industry and sports. In the 20th century in Europe and the United States, there are mature TPU waterproof and breathable clothing, special film for shoe material fitting, special film for silicone chest pads, and TPU elastic bands. It has characteristics such as high strength, good toughness, abrasion resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance and other characteristics unmatched by other plastic materials. At the same time, it has high waterproof and moisture permeability, wind resistance, cold resistance, antibacterial, mildew resistance, Many excellent features such as warmth, UV resistance and energy release.
  TPU waterproof and breathable film (high, medium, low moisture permeability) Application: Applicable to clothing, shoe materials Fabric specifications: Width: 54 "58" 60 "Thickness: Thickness 0.015mm-0.80mm, color is transparent, translucent, fog Face, milky white, complexion, black. Type: polyether, polycaprolactone Advantages: high moisture permeability, good feel, high water pressure resistance, good processing performance, washable and dry cleaning TPU waterproof breathable membrane with elastomer as the main material, its elasticity Good, high strength, waterproof properties with physical properties unmatched by other materials (can withstand water pressure above 10000mm, the thinnest can reach 0.012mm); TPU film has excellent moisture permeability in addition to high water resistance ( Human sweat can penetrate freely between thin films)
