Tetrahydrofuran (THF) CAS 109-99-9

1. The raw material of spandex synthesis reaction tetrahydrofuran itself can be polycondensation (ring-opening repolymerization by cation) into polytetramethylene ether diol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) are made into special rubber with wear resistance, oil resistance, good low temperature performance and high strength. A block polyether polyester elastic material was prepared with dimethyl terephthalate and 1, 4-butanediol. PTMEG...
