Solubility App
Main raw material for synthesizing polyurethane; used for synthesizing 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
Soluble in alcohols, esters, ketones, aromatics and chlorinated hydrocarbons. Insoluble in aliphatic hydrocarbons and water. As the molecular weight increases, the solubility performance will decrease.
PTMEG is hygroscopic. At room temperature, PTMEG can absorb up to 2wt% water according to different molecular weights.
