Product details

TPU is short for thermoplastic polyurethane elastomer in Chinese. TPU is a polymer material formed by the common reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and macromolecular polyol and low molecular polyol (chain extender). Its molecular structure is alternately composed of rigid blocks obtained by reacting diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with chain extenders and flexible segments obtained by reacting diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols. TPU is a mature environmental protection material with excellent characteristics of high tension, high tension, toughness and aging resistance. At present, TPU has been widely used in medical and health care, electronics, industry and sports, etc. It has the incomparable characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance, etc. Compared with other plastic materials. At the same time, TPU has many excellent functions such as high waterproof and moisture permeability, wind resistance, cold resistance, antibacterial, mildew resistance, heat preservation, ultraviolet resistance, energy release, etc. Thermoplastic polyurethane elastomer TPU can be divided into polyester type and polyether type according to molecular structure, and can be divided into injection molding, extrusion, blow molding, etc. according to processing methods. TPU application classification 1. TPU is mainly used for shoe materials due to its excellent elasticity and wear resistance. TPU-containing footwear is much superior to ordinary footwear in terms of wearing comfort, so it is widely used in high-end footwear, especially some sports shoes and casual shoes. 2. Thin film TPU is increasingly welcomed by people due to its superior performance and environmental protection concept. At present, TPU can be a substitute for PVC wherever PVC is used. TPU film can not only be attached to various fabrics, but also can produce products with clear outline and stable size by vacuum thermoforming. With the continuous improvement of environmental protection awareness in China, TPU has been applied more and more widely. Among them, there are areas with relatively fast growth rate: vamp lining, thermal underwear, transparent underwear, transparent shoulder straps, elastic bands and medical breathable tapes. TPU 3. Adhesive TPU adhesive belongs to one kind of polyurethane adhesive. The use of polyurethane adhesives has become quite common in Europe and America, especially in the use of footwear adhesives, polyurethane adhesives are almost used. The use of TPU adhesive in China is to obtain polyurethane adhesive after TPU is dissolved and processed. The TPU adhesive is mainly used in Guangdong, Fujian, Zhejiang and Shanghai. 4. Hoses TPU hoses are widely used as gas and oil delivery hoses for aircraft, tanks, automobiles, motorcycles, machine tools and other mechanical equipment in China due to their softness, good tensile strength, impact strength and high and low temperature resistance. Major TPU hose manufacturers are concentrated in Guangdong, Zhejiang, Jiangsu, Shandong, Hebei and other places. 5. Wire TPU provides tear resistance, wear resistance and bending characteristics. High and low temperature resistance is the key to cable performance. Therefore, in the Chinese market, TPU for high-grade cables, such as control cables and power cables, is increasingly widely used to protect coating materials for complex cables. 6. Roller polyurethane elastomer has high mechanical strength, excellent wear resistance, excellent oil resistance, acid and alkali resistance, outstanding compression resistance and makes it widely used on rollers. There are mainly the following types of rollers in China: industrial rollers, household rollers, sports equipment wheels, medical equipment wheels and toy wheels. 7. Plastic modification can be used to plasticize PA and ABS, but the cost is relatively high. 8. The main advantages of ink TPU ink are: excellent adhesion, low viscosity, good bending flexibility, excellent wear resistance, high gloss, weather resistance, resistance to any sun exposure including UV irradiation, and excellent strength, toughness and durability in various application fields. Ink made of aromatic and aliphatic TPU can be used under various climatic and environmental conditions, and the product has stable and outstanding performance. TPU ink has the characteristics of bright and smooth appearance, good shading, alcohol resistance, strong adhesive force and the like, and is mainly suitable for surface decoration of TPU and other plastics. Such as mobile phones, notebook computers, shoes, car leather chairs, sofas, high-grade leather goods, handbags, inflatable entertainment TPU products, umbrellas, raincoats and other TPU ink used on metal and glass, attach rate is poor, easy to drop paint.
