Three Kinds of Polyurethane elastomers
Polyurethane elastomer (PU) is a new kind of organic polymer materials and a new type of polymer composite materials between rubber and plastic. PU is known as "the fifth plastic" which is widely used in various industries because of its excellent properties. The main types are Casting Polyurethane Elastomer (CPU), Thermoplastic Polyurethane Elastomer (TPU) and Millable Polyurethane Elastomer (MPU).
Casting Polyurethane Elastomer (CPU) is also called thermosetting elastomer, liquid at room temperature and solid after processing. Due to the CPU has excellent abrasion resistance (the best in elastomers), so the CPU is always used for casters and the rollers of mining, oil refining, textiles and printing machine.
Thermoplastic Polyurethane Elastomer (TPU) has excellent abrasion resistance (the best in elastomers) which is the same with CPU, solid at room temperature, and liquid after heating, then solid polyurethane products after processing. TPU is the most widely used, such as sports equipment: skating shoes, buckles, accessories, snow boots; industrial components: seals, auto parts, dust tubes, pipe fittings, industrial wheels, conveyor belts; pipes: air compressor pipes, fire hoses, medical tubes, wire and cable, watchband, film; shoes material: soles, shoe accessories, air cushion, heel lift, spikes, etc.
Millable Polyurethane Rubber (MPU) has good wear resistance, good oil resistance and low temperature resistance, compressive strength and high strength and other excellent comprehensive physical and mechanical properties. They can use the general rubber processing equipment and process for processing production. MPU products are widely used in automobiles, metallurgy, electronics, textiles, machinery and other industries. The molded products contain seals, shock absorbers, rubber rollers, rubber wheels, etc. And the extruded products contain rubber strips, rubber hoses, sealing strips, special seals, etc.
