Polyurethane elastomer is called PU Elastomers in English, which is a kind of polymer material. Polyurethane is a new type of organic polymer material, known as "the fifth largest plastic", and is widely used in many fields of national economy because of its excellent properties. It is divided into casting polyurethane elastomer (CPU), thermoplastic polyurethane elastomer (TPU) and mixed polyurethane elastomer (MPU).
Pouring polyurethane elastomer (CPU) is a new polymer synthetic material between rubber and plastic. In practical application, it is often used as an updated product of rubber products. Because CPU has excellent wear resistance (the best elastomer), casting polyurethane elastomer (CPU for short) is also called thermosetting elastomer, which is liquid at room temperature and solid after processing, so CPU is often used in casting processing, such as casters and mining.
TPU thermoplastic polyurethane elastomer (TPU for short) is also a new polymer synthetic material between rubber and plastic. In practical application, it is often used as an updated product of rubber products, and also has excellent wear resistance with CPU (the best elastomer). It becomes solid at room temperature, heated or dissolved into liquid, and then becomes solid polyurethane material after processing and molding. TPU is one of the most widely used polyurethane elastomers, such as sports equipment: roller skates, shoes, buckles, accessories, snow boots ... industrial parts: seals, automobile parts (dust pipes, pipe fittings, shock absorbers, industrial wheels, conveyor belts ... pipes: pneumatic pipes, fire hoses, medical pipes ... wires and cables, belts, etc.
