Scope
Main technical content: This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, etc. of polytrimethylene ether glycol-bis(phenylglycolate) ester (hereinafter referred to as P-250). This standard applies to compounds prepared by esterifying polytrimethylene ether glycol (PTMEG) with p-aminobenzoic acid or by ester exchange reactions with p-aminobenzoic acid ester compounds, with an average molecular weight of 250. The product is mainly used as a vulcanizing agent for polyurethane elastomers, and can also be used to cure epoxy resins.
