Polytetramethylene ether glycol (PTMEG)
DESCRIPTION
Polytetramethylene ether glycol (PTMEG) is a waxy, white solid that melts to a clear, colourless, viscous liquid near room temperature. PTMEG is produced by the catalyzed polymerization of tetrahydrofuran (THF). The melting range varies according to the molecular weight.
PRODUCT GROUP
- Resins & Binders
SYNONYMS
Polytetrahydrofuran
MAJOR APPLICATIONS
The chief uses of PTMEG are in the production of spandex (polyurethane) fibers, accounting for more than 80% of global demand annually. Products made from PTMEG retain their elasticity at extremely low temperatures. Ideal applications include articles required to operate at low temperatures (drive belts, skiboots, snowmobile components, synthetic leathers, etc.) Demand for PTMEG is mainly driven by growth in textiles, adhesives & sealants, coatings and automotive sectors.
