PTMEG

Polytetrahydrofuran (PTMEG) is a primary polymer of tetrahydrofuran (THF), appearing as a white, waxy solid at room temperature. It is a linear polyether glycol characterized by its high molecular weight, excellent flexibility, and outstanding hydrolytic stability. PTMEG is renowned for producing polyurethanes with superior elasticity, toughness, and abrasion resistance, making it the preferred polyol for high-performance applications.
