Poly(tetramethylene ether)glycol

PTMG (Poly(tetramethylene ether)glycol / PTMG) is a linear polyether glycol with hydroxyl groups on both ends. As a polyol, it reacts readily with isocyanates (i.e., MDI, TDI, etc.) to produce resins with excellent properties such as impact resistance, hydrolysis resistance, wear resistance, tear resistance, fungus resistance and low temperature flexibility. The Polyurethane applications are Polyurethane Elastomers, Thermoset Elastomers (TSU), Thermoplastic Elastomers (TPU), Paints and Coatings, Adhesives and Sealants, and Artificial Suede and Synthetic Leather. The Polyester Applications are Polyester Elastomers (TPEE), Polyamide Applications and Polyether Amide Elastomers.
