Polytetramethylene ether glycol (PTMEG) is a waxy, white solid that melts to a clear, colorless, viscous liquid near room temperature. PTMEG is produced by the catalyzed polymerization of tetrahydrofuran (THF). The chief uses of PTMEG are in the production of spandex (polyurethane) fibers, polyurethane elastomers, and copolyester-ether elastomers.
The majority of new plants and capacity expansions have taken place in China, to supply the country's rapidly growing market for spandex. Chinese PTMEG production capacity doubled between 2012 and 2015. China currently accounts for about 59% of global capacity, about 57% of global consumption, and about 48% of global production.
