TPU not only has excellent high tension, the characteristics of high strength, toughness and resistance to aging, and it is the mature environmental protection material, at present, the TPU has been widely used in medical and health and sports, etc., it has unmatched by other plastic materials, high strength, good toughness, wear-resisting, cold resistant, oil resistant, water resistant, ageing resistance, weather resistance and other properties, at the same time, he has high waterproof moisture permeability, wind, cold, antibacterial, mouldproof, heat preservation, anti-ultraviolet radiation and energy release many excellent features.
PU film is a non - toxic and environmentally friendly polymer elastomer film with high strength, abrasion resistance, elasticity, resistance, environmental protection and non-toxic recovery and decomposition. Polyurethane film has excellent properties such as high transmittance, constant yellow, weather resistance, high adhesion relay, high extension length and high elasticity. So can special design with a variety of thermoplastic composite film, including polycarbonate, methyl acrylic acid, etc., to form a high-level sputtering bulletproof, explosion-proof and riot sandwich glass, give full play to both light and thin and high impact resistance characteristics. Some series of films have extremely high elasticity. The tensile strength of some series is as high as 300 pounds per inch, and the maximum elongation is up to 600%. Thus can effectively absorb the impact energy, and its wide range of applications including: Banks, politicians and the office of the embassy and residence, prisons, bulletproof, cash, jewelry store, museums, ultra high speed train, air space, military, typhoon resistant glass, LCD compound layer, a computer screen, the zoo, etc.
TPU film mainly USES the process for the preparation of such as extrusion, rolling and blowing, due to the characteristics of molecular structure of polyurethane, people can adjust the polyurethane block composition change its elasticity, hardness and hydrophilicity. It is very suitable for heat pressing, high frequency wave, sewing, or adding the following agent. Besides, this material can also be used in printing ink, vacuum or high cycle. The products are widely used in many fields such as health care, shoes, bags, sports equipment, automobile industry, readymade garments, gloves, blown gas products, high grade textile fabrics and so on.
TPU film is a thin film made of TPU particle based on the special process of rolling, extending, blowing film and coating.
TPU (Thermoplastic polyurethanes), thermal plasticity TPU elastomer, by including NCO functionality, MDI and OH functionality, POLYOL, 1.4 BG, made by mixing and extruding, with good elasticity, good physical properties, and a variety of mechanical strength is very good, therefore, widely used in injection, extruding, rolling and dissolved into solution such as resin processing way, is the plastic processing industry often use plastic material, made its products cover the range of industrial applications and civil necessities.
In recent years, due to the continuous development of new products, the amount of thermoplastic PU elastomer is continuously increasing, which is a new opportunity for the industry of plastic processing industry to create low cost and high value added value.
TPU (thermal plasticity polyurethane) is increasingly popular because of its superior performance and environmental protection concept. At present, any place where PVC is used, TPU can be used as a substitute for PVC. However, TPU has the advantages of PVC. TPU not only has excellent high tension, high tension, toughness and aging resistance, but also a mature environmental protection material. At present, the TPU has been widely used in: shoe, garment, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat material, umbrellas, suitcase, leather bags, etc.
TPU film is based on TPU particle material, which is made into thin films by means of rolling, rolling, film and coating. At present, it is widely used in sports shoes, such as trademark decoration, air bag, air cushion, oil bag, etc.
Today, TPU film on sneakers application has two trends: one is to blow by the female sandals fashion, that is, high will be transparent TPU film or cutting directly, or coloring, screen printing or joint duct into net cloth, etc., high frequency shaping and glue on the shoes, there are functional and decorative effect. Second, the waterproof and moistureproof TPU thin film and shoe material are used to apply, to achieve the waterproof and moisture permeable effect.
