Product Details

PTMEG belongs to the class of polyetherpolyols which have excellent reactivity.

Thanks to its own brand new manufacturing method, Korea PTG consistently produces high quality PTMEG products in continuous process. 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.
