TPU Film Compared With Other Plastic Materials

Date:May 14, 2019

TPU (Thermoplastic polyurethanes), thermoplastic TPU elastomer, is made by MDI containing NCO functional group and POLYOL and 1.4BG containing OH functional group. It is made by kneading and mixing. It has good elasticity, good physical properties and various mechanical strengths. They are very good. Therefore, they are widely used in injection, extrusion, calendering and dissolution into solution-type resins. They are plastic materials that are often used by plastics manufacturers. The products are made up 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: 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. TPU film is in TPU particles On the basis of the material, the film is formed 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.

Nowadays, TPU film has two trends in sports shoes: one is the popular wind blown by women's sandals, that is, the high transparent TPU film is directly cut, or screen printing, or cloth The base is formed into a mesh cloth, etc., and the high frequency is formed and bonded to the upper, which has functional and decorative effects. The second is to use the waterproof and moisture-permeable TPU film and the shoe material to be used together to achieve the effect of waterproof and moisture permeability.

Compared with PVC, EVA, butyl rubber and other plastic materials, TPU not only has environmentally friendly, non-toxic, anti-mild, anti-corrosion, bio-compatible and other excellent characteristics, but also resistant to tortuous tears, acid and alkali resistant oil, anti-aging Oxidation, wide weather resistance and other properties are also very excellent. TPU film is one of the mainstream environmental protection materials in the 21st century with its unparalleled advantages.
