TPU (thermoplastic polyurethane) is increasingly popular for its superior performance and environmentally friendly concepts. At present, TPU can be a substitute for PVC wherever PVC is used. But the advantages of TPU, PVC is no more. TPU not only has excellent high tension, high tensile strength, toughness and aging resistance, but also is a mature environmentally friendly material. At present, TPU has been widely used in: shoe materials, garments, inflatable toys, sports equipment for water and underwater, medical equipment, fitness equipment, car seat materials, umbrellas, luggage, leather bags and so on. Film/sheet TPU film is widely used in sports shoes: trademark decoration on the sole and upper, airbags, air cushions, oil bags, etc. Nowadays, there are two trends in the application of TPU film on sports shoes. One is the popular style of Nike sneakers, which is to screen the TPU film first, then form it with high frequency and bond it to the upper. Decorate to achieve special decorative effects. The second is to use waterproof and moisture-permeable TPU film and shoe cloth to use together to achieve waterproof and moisture-permeable effect. TPU grain The thermoplastic TPU elastomer is made of MDI containing NCO functional group and POLYOL and 1.4BG containing OH functional group. It is made by kneading and kneading. Because of its good elasticity, good physical properties and excellent mechanical strength, it is widely used. It is used for injection, extrusion, calendering and dissolving into a solution-type resin. It is a plastic material that is often used by the plastics industry. Its products cover the range of industrial applications and people's livelihoods. In recent years, due to the continuous development of new products, the use of thermoplastic PU elastomers is continuously increasing, creating a new opportunity for the plastics industry to create low-cost, high value-added industries.
