Polyurethane (PU), full name for polyurethane, is a high polymer compound. Polyurethane has polyester type and polyether type. They can be made of polyurethane plastics (mainly foam plastics), polyurethane fibers (China called spandex), polyurethane rubber and elastomers.

  flexible polyurethane mainly has linear structure of thermoplastic, it has better stability, chemical resistance, resilience and mechanical properties than PVC foam material, and has less compression deformation. Heat insulation, sound insulation, anti-seismic, anti-virus performance is good. Therefore, it is used as packaging, sound insulation and filtering materials. Rigid polyurethane plastic is light, sound insulation, superior thermal insulation performance, chemical resistance, good electrical performance, easy processing, low water absorption. It is mainly used in construction, auto, aviation industry, thermal insulation structural materials. The properties of polyurethane elastomer are between plastic and rubber, oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness and elasticity. It is mainly used in 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, the material has been widely used in the field of home furnishings, construction, daily necessities, transportation, household appliances and so on.

  with the enhancement of global awareness of environmental protection, Youyang Zhisu began to seek transformation, taking building green and environmentally friendly polyurethane production process as the main development direction, and gradually eliminating backward production capacity. It is expected that in the next few years, Youyang Zhisu polyurethane bearing products will be mainly used in the fields of construction, transportation equipment, medical equipment, packaging machinery, furniture and sports.
