Solubility Application

The main raw material for the synthesis of polyurethane; used It is suitable for synthetic spandex, PU resin, water-based PUD, CPU, TPU, etc., and has good hydrolysis resistance.
Excellent physical and chemical properties such as high elasticity, wear resistance and low temperature resistance.

Hygroscopicity solubility
Can be dissolved in alcohol, esters, ketones, aromatic hydrocarbons and chlorinated hydrocarbons. Insoluble in aliphatic hydrocarbons and water. As the molecular weight increases, the solubility will decrease.
PTMEG is hygroscopic. At room temperature, PTMEG can absorb up to 2wt% of water according to different molecular weights.
