Solubility Application
The main raw material for synthetic polyurethane; used to synthesize spandex, PU resin, water-based PUD, CPU, TPU, etc., with 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.
