- 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
