What is Polyurethane
Polyurethane (PU), full name polyurethane, is a polymer material with excellent mechanical properties formed by polyol and polyisocyanate through polycondensation reaction,and is extremely plastic. Its synthesis can be traced back to 1937, when Prof. Byaer first synthesized straight-chain linear polyurethane resins using 1,6-hexanediisocyanate and 1,4-butanediol as raw materials. Several major classifications of polyurethanes include polyether-type, polyester-type, polyimide-type, and polyurea-type, etc. They can be made into materials such as polyurethane plastics (mainly foams), polyurethane fibers (known as spandex in China), polyurethane rubbers, and elastomers.
After nearly eighty years of technological development, polyurethane materials have a wide range of applications involving products such as coatings, adhesives, fabric finishing agents, leather modifiers, polyurethane soft/rigid foam, elastomers, etc., which are used in the fields of textile, construction, aviation, shipbuilding, transportation, medicine and electronics. Flexible polyurethane mainly has a linear structure with thermoplasticity, which has better stability, chemical resistance, resilience and mechanical properties than PVC foams, with less compression variability. Heat insulation, sound insulation, shock resistance, anti-virus performance is good. Therefore, it is used as packaging, sound insulation and filtering materials. Rigid polyurethane plastic is lightweight, sound insulation, superior thermal insulation performance, chemical resistance, good electrical properties, easy processing, low water absorption. It is mainly used in construction, automobile, aviation industry, thermal insulation structure materials. Polyurethane elastomer performance between plastic and rubber, oil resistance, abrasion resistance, low temperature resistance, aging resistance, high hardness, elasticity. It is mainly used in the shoe industry and the medical industry. Polyurethane can also make adhesives, coatings, synthetic leather, etc.
