[0002] The full name of polyurethane is polyurethane. It is a polymer material with excellent mechanical properties and strong plasticity formed by polyols and polyisocyanates through condensation reaction. Its synthesis can be traced back to 1937, when Professor Byaer first synthesized straight-chain linear polyurethane resin using 1,6-hexamethylene diisocyanate and 1,4-butanediol as raw materials. The main classifications of polyurethane include polyether type, polyester type, polyimide type, polyurea type, etc. They can be made into polyurethane plastics, polyurethane fibers, polyurethane rubbers, elastomers and other materials. Chain extenders, also known as chain growth agents, are substances that can react with functional groups on linear polymer chains to extend the molecular chains and increase the molecular weight. They are often used to improve the mechanical properties and process properties of polyurethane, polyester and other products.
