What is TPU? What's the use?

In recent years, due to the continuous development of new products, the consumption of thermoplastic polyurethane elastomer has been increasing, which has created new opportunities for plastic processors with low cost and high added value. TPU (thermoplastic polyurethane) is becoming more and more popular because of its superior performance and environmental protection concept. At present, TPU can replace PVC wherever it is used. But the advantage of TPU, PVC is far behind. TPU not only has excellent characteristics of high tensile strength, high toughness and aging resistance, but also is a mature environmental protection material. At present, TPU has been widely used in shoes, clothing, inflatable toys, underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, wallets and so on. TPU film is made of TPU particles through calendering, casting, film blowing, coating and other processes. At present, it is widely used in sports shoes: trademark decoration of soles and uppers, airbags, air cushions, oil bags and so on. At present, there are two trends in the application of TPU film in sports shoes: one is the popular trend caused by women's sandals, that is, the TPU film with high transparency is directly cut, screen printed, colored, or attached to a cloth base to form a sandwich mesh cloth. And is molded and bonded to the vamp with high frequency, which has functional and decorative effects. Secondly, the waterproof and moisture-permeable TPU film is used with the cloth for shoe materials to achieve the waterproof and moisture-permeable effect. Characteristics The main characteristics of TPU are: wide hardness range: products with different hardness can be obtained by changing the proportion of various reaction components of TPU, and with the increase of hardness, their products still maintain good elasticity and wear resistance. High mechanical strength: TPU products have outstanding bearing capacity, impact resistance and shock absorption. Outstanding cold resistance: the glass transition temperature of TPU is relatively low, and it still maintains good physical properties such as elasticity and flexibility at MINUS 35 degrees. Good processability: TPU can be processed by common processing methods of thermoplastic materials, such as injection molding, extrusion and calendering. At the same time, TPU can be processed with some polymer materials to obtain polymer alloys with complementary properties. TPU is oil-resistant, waterproof and mildew-proof. Good recovery performance. Uses of various TPU molding products: spherical coupling for automobile parts; Dust cover; Pedal brake; Door lock striker; Bushing leaf spring bushing; Bearing; Shock-proof parts; Interior and exterior decorative parts; Snow chains and other mechanical and industrial parts, all kinds of gears; Sealing (mainly for wear resistance and oil resistance); Shock-proof parts; Mold-taking needle; Casing; Bearing cover; Connector; Rubber screen; Printing cots and other garment accessories, ladies' bra shoulder straps, garment elastic bands, etc. Footwear: softball shoes, baseball shoes, golf shoes, football shoe soles, ladies' forefoot heels; Ski boots; Self-aligning wheels such as safety boots and high-grade soles; Handle; Watchbands and other pipes, hoses and high-pressure pipes; Medical management; Oil pressure pipe; Pneumatic tube; Fuel pipe; Coating pipe conveying pipe; Rotating belt of membrane and plate such as fire hose (with certain stretching effect); Air cushion; Diaphragm; Keyboard; Composite cloth and other wires and cables, power communication cables; Computer wiring; Automobile wiring; Exploration cables and other various annular pipelines; Annular belt; V-belt; Synchronous belt; Non-slip belts and other calendered soft grooves and grooves; Film composite sheets, luggage fabrics and other blow molding boxes for various vehicles; All kinds of containers blow film ultra-thin and wide film (medical and health supplies) to dissolve welding materials; Adhesive; The coating TPU of artificial leather, synthetic leather, rope, iron wire and gloves is thermoplastic polyurethane, which is divided into polyester type and polyether type. It has a wide hardness range (60HA-85HD), wear resistance, oil resistance, transparency and good elasticity, and is widely used in daily necessities, sporting goods, toys, decorative materials and other fields. Halogen-free flame retardant TPU can also replace soft PVC to meet the environmental protection requirements in more and more fields. There are many TPU brands with uneven quality. When selecting TPU, it is best to go through detailed evaluation and demonstration, otherwise the best cost-effective result cannot be obtained.
