    Polyurethane (PU), full name of polyurethane, is a kind of macromolecular compound. It was made by Otto Bayer in 1937. Polyurethane is divided into polyester type and polyether type. They can be made into polyurethane plastic (mainly foam plastic), polyurethane fiber (called spandex in China), polyurethane rubber and elastomer. Soft polyurethane is mainly a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical properties than PVC foam materials, and has less compression deformation. Good heat insulation, sound insulation, shock resistance and anti-virus performance. Therefore, it is used as packaging, sound insulation and filtering materials. Rigid polyurethane plastic is light in weight, excellent in sound insulation and heat insulation, chemical resistance, good in electrical performance, easy to process, and low in water absorption. It is mainly used in construction, automobile, aviation industry and thermal insulation structural materials. The performance of polyurethane elastomer is between plastic and rubber, which is resistant to oil, abrasion, low temperature, aging, high hardness and elasticity. It is mainly used in footwear industry and medical industry. Polyurethane can also be used to make adhesives, coatings, synthetic leather, etc

    Thermoplastic elastomer has the physical and mechanical properties of vulcanized rubber and the processing properties of soft plastics. As the rubber no longer needs to be heat vulcanized, the final product can be easily made using simple plastic processing machinery. With this feature, the production process of rubber industry has been shortened by 1/4, energy consumption has been saved by 25%~40%, and efficiency has been improved by 10~20 times. It can be called another material and process technology revolution in rubber industry. Thermoplastic elastomer is a new polymer material between rubber and resin. It can not only replace part of rubber, but also modify plastics. Thermoplastic elastomer has the dual properties and broad characteristics of rubber and plastic, which makes it widely used in the rubber industry to manufacture daily products such as rubber shoes and adhesive tapes, and various industrial products such as rubber hoses, tapes, rubber strips, rubber sheets, rubber parts and adhesives. At the same time, thermoplastic elastomer can also replace rubber and be widely used in the modification of general thermoplastic resins such as PVC, PE, PP, PS, and even engineering plastics such as PU, PA, CA, making the plastic industry a new situation.

    4Inch Chair Universal Platform Trolley Furniture TPR Soft Grey Rubber Plate Swivel Caster Wheels with Brake

    This type of caster features gray non-marking injection molded rubber that is mechanically and chemically bonded to the hub. They are especially suited for use in Pharmaceutical Laboratories, Hospitals, Food Service and other Institutional applications. The wheels provide a softer ride than polyurethane and yet withstand exposure to many chemicals and solvents.

    It has the same elasticity as rubber and does not need vulcanization. SBS Blending modified granulation product is called TPR, SEBS blending modified granulation product is called TPE. They are round or oval transparent particles.
