Chapter 1 TPU raw materials 1. TPU is formed by the reaction and polymerization of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and other diisocyanate molecules with macromolecular polyols and low-molecular polyols (chain extenders). Of polymer materials. Its molecular structure is a rigid block formed by the reaction of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with a chain extender and diisocyanates such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) The flexible chain segments obtained by the reaction of molecules and macromolecular polyols are alternately formed. TPU has excellent characteristics of high tension, high tensile strength, toughness and aging resistance, and is a mature environmentally friendly material. At present, TPU has been widely used in medical and health, electronic appliances, industry and sports, etc. It has high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, and aging resistance that other plastic materials cannot match.
