Polytetramethylene Ether Glycol (PTMEG) is a high-performance Polymer Grade polyether polyol available in various molecular weights (e.g., 650, 1000, 2000). Offering High Chemical Stability, it is the critical soft segment for high-performance polyurethanes.
This waxy white solid (at room temperature) melts into a clear liquid upon heating. It is renowned for imparting superior elasticity, high tensile strength, and exceptional resistance to abrasion and fungal attack in finished polyurethane elastomers.
PTMEG-based polyurethanes exhibit excellent low-temperature performance and hydrolytic stability compared to polyester-based alternatives. It is a vital raw material for the production of Spandex fibers, high-durability wheels, and specialized medical devices.
SoleChem, an ISO 9001:2015 certified chemical supplier based in Türkiye, delivers Polytetramethylene Ether Glycol (PTMEG) (CAS 25190-06-1) to customers in more than 40 countries.
