POLYMEG® 2000 POLYOL are diols produced through the polymerization of tetrahydrofuran. They are linear in structure with a backbone of repeating tetramethylene units connected by ether linkages.
The chains are capped with primary hydroxyl units.
POLYMEG 2000 POLYOL are characteristically white, waxy solids at room temperature. They do not have sharp melting or solidification points. At
slightly elevated temperatures (38° C, 100° F), they liquefy to low-viscosity, water white liquids with a tendency to supercool. The hygroscopic nature of polyols requires limiting exposure to atmospheric moisture. An antioxidant is added to POLYMEG polyols to improve the stability of the polyol against thermal and oxidative degradation during normal storage and handling.
The primary applications for POLYMEG 2000 POLYOL are as the soft segment of polyurethanes, copolymer polyesters and polyamide elastomers. As a component of urethane elastomers, the polyols are used in the following systems - Thermoplastics for injection molding and extrusion, thermoset polyurethanes, castable prepolymers, millable gums, metal and textile coatings/linings and adhesives, spandex elastic fibers.
High performance elastomers made with POLYMEG 2000 POLYOL are used in a large number of applications, including- automotive, adhesives and Sealants, coatings, engineered Components, industrial, sports equipment, clothing.
Polytetramethylene ether glycol. Diols produced through the polymerization of tetrahydrofuran, white, waxy solids at room temperature. used in automotive, adhesives and Sealants, coatings, engineered Components, industrial, sports equipment, clothing.
