[Offer PDF] Polytetramethylene Ether Glycol (PTMEG)
Chemical Economics Handbook
June 2019

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 two largest global PTMEG ̶ producers5BASF and Dairen Chemical Corporation (Chang Chun Group) ̶ together accounted for about 45% of world capacity at the end of 2018. Hyosung Corporation ranked third with almost 10%, followed by Sinopec Great Wall Energy & Chemical with 6.5%. The LYCRA Company (formerly INVISTA’s Apparel & Advanced Textiles business) was the fourth-largest producer prior to 2012 and remains a major consumer of PTMEG, but in lieu of new plants following the capacity reduction in Western Europe, the company has licensed its process technology to producers in China in exchange for long-term supply agreements.

Growth in PTMEG capacity was mild compared with the previous three years, and no additional capacities have been announced through 2023. Additions during 2016-18 were made in China and Vietnam.

The following pie chart shows world consumption of PTMEG:
