Polymeg® 1000

Polymeg® 1000 by LyondellBasell is a diol produced through the polymerization of tetrahydrofuran. It is linear in structure with a backbone of repeating tetramethylene units connected by ether linkages. The chain is capped with primary hydroxyl units. At slightly elevated temperature (38°C, 100°F), Polymeg® 1000 liquefy to low-viscosity, water white liquid with a tendency to supercool. The hygroscopic nature of polyol requires limiting exposure to atmospheric moisture. An antioxidant is added to it, to improve the stability of the polyol against thermal and oxidative degradation during normal storage and handling. Recommended for polyurethane articles and for coating applications.
