The formulation of polyurethane foam with a polymeric polyol obtained from glycolysis of poly ethylene terephthalate pet

摘要

The formulation of polyurethane foam with a polymeric polyol obtained from the glycolysis of poly ethylene terephthalate pet in the process of obtaining polyol from glycolysis of pet is known in academic circles and industrial, and many academic articles have been produced Respect,However, without conclusive results for industrial application, belonging to the field of engineering of production with correlation to chemical engineering, this patent concerns the adaptation of the polymeric polyol, this achieved from the glycolysis of pet, but adapted chemically to React with isocyanates, resulting in Dai, polyurethane foams.
