PTMEG: Polytetramethylene Ether Glycol

CAS NO.: 25190-06-1  

Capacity: 92 kt/year

PTMEG, also known as polytetrahydrofuran (PTMG), is a linear polyether diol made from tetrahydrofuran (THF) by ring-opening polymerization. As the core raw material of high-performance polyurethane, PTMEG has an irreplaceable position in high-end fields such as spandex and elastomers due to its low-temperature elasticity, hydrolysis resistance and adjustable molecular weight. In the future, with the breakthrough of bio-based processes and the upgrading of environmental protection demands, PTMEG will continue to promote the green and high-performance development of the polyurethane industry.
