Polytetramethylene Ether Glycol (PTMEG) is the premier polyether polyol used worldwide in the manufacture of high-performance polyurethane elastomers. Known for its unique performance attributes and processing advantages, PTMEG is used in a variety of applications across multiple industries. These applications include polyurethane and polyurea resins, prepolymers, coatings, adhesives, cast polyurethane resins, TPUs, spandex fibers, and more. Compared with PPG-based polyols, PTMEG-based polyurethanes exhibit strain-induced crystallization in the soft segments and exact di-functionality, leading to significant enhancements in performance.
