Remark The polyester polyol of PET plastic bottle chips is recycled by chemical degradation manufacturing and recycling process to ensure the stable quality of PET materials. Used in B1 and B2 spray and sheet formulations. Phthalic anhydride polyester polyol It is mainly used in the production of polyurethane rigid foam plastics and the preparation of PIR and PUR foams with high temperature resistance and flame retardancy. A phosphorus-halogen synergistic aromatic flame-retardant polyester polyol. It is mainly used to produce polyurethane rigid foam plastics with high flame retardancy. The invention relates to a high-functionality polyester polyol which is mainly used for producing polyurethane rigid foam plastics and preparing PIR and PUR foam with high temperature resistance and flame retardance. A phosphorus-halogen synergistic aromatic flame-retardant polyester polyol. It is mainly used to produce polyurethane rigid foam plastics with high flame retardancy.
