Product Description
Polyurethane (PU), the full name is polyurethane, is a polymer compound. It was made by Otto Bayer in 1937.Polyurethane is divided into two categories: polyester type and polyether type. They can be made into polyurethane plastics (mainly foamed plastics), polyurethane fibers (called spandex in China), polyurethane rubbers and elastomers. 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. It has good thermal insulation, sound insulation, shock resistance and anti-virus performance. Therefore, it is used as packaging, sound insulation, filter material. Rigid polyurethane plastic is light in weight, excellent in sound insulation and thermal insulation, chemical resistance, good electrical properties, easy processing, and low water absorption. It is mainly used in construction, automobile, aviation industry, thermal insulation structural materials. The performance of polyurethane elastomer is between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. Mainly used in shoe industry and medical industry. Polyurethane can also be used to make adhesives, coatings, synthetic leather, etc. Polyurethane appeared in the 1930s. After nearly 80 years of technological development, this material has been widely used in the field of home furnishing, construction, daily necessities, transportation, and home appliances.Product specification
