TPU waterproof breathable membrane introduction and classification

TPU is the abbreviation of "Thermoplastic Urethane". TPU is made of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), polymer polyol and chain extender. Polymeric material. Its molecular structure is a rigid block obtained by the reaction of diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and chain extender, and diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI) and macromolecules. TPU has excellent high tension, high tensile strength, toughness and aging resistance. TPU is a mature and 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 plastic, but also has excellent comprehensive physical and chemical properties, so it is also known as the material of the future.TPU film is a film made of TPU particles 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 care, electronics and electrical appliances, industry and sports, etc. In the 20th century, Europe and the United States have mature TPU waterproof and breathable clothing, shoes laminated special film, silicone breast pads special film, TPU elastic band. With high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance and other plastic materials can not be compared to the characteristics. At the same time, it has many excellent characteristics such as high waterproof and moisture permeability, wind resistance, cold resistance, antibacterial, anti-mildew, warmth, UV resistance, energy release, etc.
  TPU waterproof breathable film (high, medium and low moisture permeability) Application: Suitable for clothing, shoe fabrics Specifications: Width: 54" 58" 60" Thickness: Thickness 0.015mm-0.80mm, Color transparent, translucent, matte, milky white, skin color, black. Type: polyether, polycaprolactone advantages: high moisture permeability, good feel, high water pressure resistance, good processing performance, washable and dry-cleanable TPU waterproof breathable film with elastomer as the main material, its good elasticity, with other materials can not be compared to the physical properties of high strength, waterproof performance (can withstand more than 10,000mm of water pressure, the thinnest up to 0.012mm); TPU film has high water resistance in addition to TPU film not only has high water resistance, but also has excellent moisture permeability (human sweat can freely penetrate between films)
  Uses: Mainly used in various bonding on clothing fabrics: windbreaker, raincoat, shoes, hats, gloves, cold-proof clothing, ski gloves, morning bags, gift bags, cell phone wipes, leisure products, sporting goods, military defense and medical equipment are used.
