TPU (Thermoplastic Polyurethanes), a thermoplastic TPU elastomer, is made by mixing MDI containing NCO functional groups with POLYOL and 1.4BG containing OH functional groups, and is made by kneading and kneading. It has good elasticity, good physical properties and various mechanical strengths. It is very good. Therefore, it is widely used in injection, extrusion, calendering and dissolving into solution type resins. It is a plastic material often used by plastics processing industry. Its products cover the range of industrial applications and civilian necessities. 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.
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 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.
The TPU film is formed on the basis of TPU pellets by calendering, casting, film blowing, coating, and the like. At present, it is widely used in sports shoes: trademark decoration on the sole and upper, airbags, air cushions, oil bags, etc.
TPU shoes, TPU film has two trends in the application of sports shoes:
The first is the popular style of women's sandals, that is, the high-transparent TPU film is directly cut, or screen printing, or laminated to a mesh cloth, etc., high-frequency forming and bonding on the upper , functional and 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.
