Background

Polyurethane (PU), the full name of which is polyurethane, is a high molecular compound. This product was produced in 1937 by Otto Bayer et al. Polyurethanes fall into the two main categories of polyester and polyether. They can be made into polyurethane plastics (mainly foamed plastics), polyurethane fiber (Chinese called spandex), polyurethane rubber and elastomer. The soft polyurethane mainly has a thermoplastic linear structure, and has better stability, chemical resistance, rebound resilience and mechanical property and smaller compression deformability than a PVC foaming material. Good heat insulation, sound insulation, shock resistance and gas defense performance. Therefore, the product is used as a packaging, sound insulation and filtering material. The hard polyurethane plastic has the advantages of light weight, excellent sound insulation and heat insulation performance, chemical resistance, good electrical property, easy processing and low water absorption rate. It is mainly used as a heat-insulating structural material in the building, automobile and aviation industries. The polyurethane elastomer has the performance between that of plastic and rubber, and has the advantages of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. Is mainly used in the shoe making industry and the medical industry. The polyurethane can also be used for preparing adhesives, coatings, synthetic leather and the like. Polyurethane appears in the 30 s of the 20 th century, and through the technical development of nearly eighty years, the material is widely applied to the fields of home furnishing, buildings, daily necessities, traffic, household appliances and the like.
