PU is an emerging organic polymer material that is widely used in many fields of the national economy due to its excellent performance.
It is divided into cast polyurethane elastomer (referred to as CPU), thermoplastic polyurethane elastomer (referred to as TPU), and mixed polyurethane elastomer (referred to as MPU).
CPU: Cast polyurethane elastomer (CPU) is a new type of polymer synthetic material between rubber and plastic. In practical applications, it is mostly used as a replacement product for rubber products. Because CPU has excellent durability Abrasion resistance (the best among elastomers), cast polyurethane elastomer (CPU for short) is also called thermosetting elastomer. It becomes liquid at room temperature and becomes solid after processing. Therefore, CPU is often used for casting processing, such as casters, Mining, oil refining, textile, printing machine rollers, the finished products are strong in wear resistance.
TPU: Thermoplastic polyurethane elastomer (TPU for short) is also a new type of polymer synthetic material between rubber and plastic. In practical applications, it is mostly used as a replacement product for rubber products and is also related to CPU. Excellent wear resistance (the best among elastomers), it becomes solid at room temperature. It becomes liquid by heating or solution. After processing and shaping, it becomes a solid polyurethane material again.
TPU is the most widely used and produced type of polyurethane elastomer, such as sports equipment: skate wheels, skates, buckles, accessories, and snow boots. Industrial parts: seals, auto parts (dust-proof pipes, pipe fittings, shock absorbers, industrial wheels, conveyor belts. Pipe materials: air pressure pipes, fire water pipes, medical pipes...wires and cables, strips, watch straps, films. Shoe materials : Soles, shoe trims, air cushions, accessories, leather, spikes, labels, etc.
