Low price Polyurethane elastomer, which is formed by chain extension of isocyanate prepolymer prepared by the reaction of composite polyol and organic isocyanate, the composite polyol is composed of polyester polyol and polyether polyol, and the polyester polyol is composed of polyester polyol and polyether polyol. The alcohol is formed by the polycondensation of dibasic acid, propylene glycol and ethylene glycol, the polyether polyol is formed by the polymerization of ethylene oxide and/or propylene oxide, and the organic isocyanate is made of ethylene oxide and/or propylene oxide. It is composed of aromatic isocyanate and aliphatic isocyanate, and the chain extender used for chain extension is amine chain extender. Based on the theory of polyurethane structure and performance, the present invention adopts well-known prepolymerization, casting molding, and bulk synthesis of solvent-free and environmentally friendly Low price Polyurethane elastomer, this Low price Polyurethane elastomer has ultra-high ultimate elongation at break (greater than 1000%) to meet applications in special fields such as special bonding, shock absorption and sealing.
The above is a brief introduction to the relevant knowledge about Low price Polyurethane elastomer.
