TPU film compared with other plastic materials is very worthy of praise

From RainbowTPU

TPU (thermoplastic polyurethane), thermoplastic TPU elastomer, made of MDI containing NCO functional groups and POLYOL and 1.4bg containing OH functional groups. It is made by kneading and mixing. It has good elasticity, good physical properties and various mechanical strength. They're fine. As a result, they are widely used for injection, extrusion, calendering and dissolution into solution resins. They are often used by plastic manufacturers. The product consists of industrial applications and civil necessities. In recent years, due to the continuous development of new products, the use of thermoplastic PU elastomer has been increasing, which provides new opportunities for the plastics industry to create low-cost and high-value-added industries. And TPU (thermoplastic polyurethane) is increasingly popular for its superior properties and environmentally friendly concepts.At present, no matter where PVC is used, TPU can replace PVC, but the advantages of TPU and PVC are far behind. TPU not only has excellent high tension, high tensile strength, toughness and aging resistance, but also is a mature environmental protection material. At present, TPU has been widely used in: shoes materials, garments, inflatable toys, sports equipment above and below water, medical equipment, fitness equipment, car seat materials, umbrellas, bags, bags and leather goods and other IPU film is on the basis of TPU particle material, film is formed through rolling, casting, film blowing, coating and so on. At present, it has been widely used in sports shoes: sole and uppers logo decoration, airbags, air cushion, oil bags and so on.

Nowadays, there are two trends in the application of TPU film in shoes: one is the wind blowing in women's sandals, that is, directly cutting high transparent TPU film or screen printing, or laminating cloth into mesh cloth, etc., and then forming a high frequency and gluing to the upper of the shoes, which is functional and decorative. The second is to use waterproof and moisture permeable TPU film and shoe materials together to achieve the effect of water resistance and moisture permeability. And compared with PVC, EVA, butyl rubber and other plastic materials, TPU is not only environmentally friendly, non-toxic, mild resistance, corrosion resistance, biological compatibility, etc., but also to twists and turns, acid, alkali resistance, aging resistance, oxidation resistance, weather resistance and other properties are very excellent. TPU film with its unparalleled advantages has become one of the mainstream environmental protection materials in the 21st century.
