Description

PTMEG((Polytetramethylene Ether Glycol)) 250

1. Description

As a compound of THF, it is transparent liquid with viscosity at a temperature higher than ambient temperature. The PTMEG is mainly used as a raw material of Polyurethane, Elastomer, Polyester Elastomer and Spandex fabric. We have a standard range of PTMEG products such as 250, 650, 1000, 1800, 2000, 3000 etc. in terms of molecular weight, whilst a customized product between 250 and 3000 can also possibly be produced based on a special order.


2. Synonyms
Poly(Oxytetramethylene) Glycol, Polytetramethylene Oxide(PTMO), Polybutylene Glycol, Polytetrahydrofuran(PTHF)
