Polytetramethylene Ether Glycol
- Applications of PTMEG
PTMEG is a product generated from polymerization of THF via facilitation of acidic medium. It is a linear chain diol with repetitive connections of tetramethylene ether that features excellent elasticity, low temperature and hydrolysis resistance. The main applications are:
(1) Manufacturing of Spandex
(2) PU elastic
(3) Synthetic leather
(4) Paint and coating
