VORANOL™ 490 Polyol

A 4.3 functional, sucrose/glycerine initiated polyether polyol designed for the production of rigid polyurethane foam. It is suitable for both high and low density foams. This product can be used alone, or in combination with other polyols or fire retardant agents, to achieve various degrees of crosslinking. This polyol is very compatible with many different types of isocyanates. This product results in foams with excellent K-factors-to-flowability relationships. Typical applications include appliance insulation, insulated panels, refrigerated transportation vehicles, portable coolers, pour-in-place insulation, marine floatation, polyol blends.
