TPU (thermoplastic polyurethane) is increasingly popular for its superior performance and environmentally friendly concepts. At present, wherever PVC is used, TPU can be a substitute for PVC. But the advantages of TPU, PVC is far behind. 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: shoe materials, ready-to-wear, inflatable toys, sports equipment for water and underwater, medical equipment, fitness equipment, car seat materials, umbrellas, luggage, leather bags, etc.
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.

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 solution type resins. It is a plastic material commonly used by plastics manufacturers. 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.
