Product Application of Poly(tetrahydrofuran)CAS#25190-06-1

As an important chemical raw material, polytetrahydrofuran is mainly used to prepare spandex in the chemical fiber field, and in the non-fiber field for the preparation of elastomers, adhesives, coatings, sealants and other fields. The polyurethane products prepared with it are wear-resistant, chemical-resistant, and have good flexibility and resilience. At present, the top three uses of polytetrahydrofuran abroad are polyurethane elastic fiber (49%), polyurethane elastomer (36%) and ester-ether copolymer elastomer (15%).
