Product Description
Polytetramethylene ether glycol (PTMEG) is a waxy, white solid that melts to a clear, colorless, viscous liquid near room
temperature. Polytetramethylene ether glycol is produced by the catalyzed polymerization of te trahydrofuran (THF). The chief uses of Polytetramethylene ether glycol are in the production of spandex (polyurethane) fibers, polyurethane elastomers, and copolyester-ether elastomers.
Applications of PTMEG
Use of PTMEG are in the production of spandex (polyurethane) fibers, polyurethane elastomers, TPU, and copolyester-ether elastomers.
