Title: POLYURETHANE AND POLYISOCYANURATE FOAMS AND METHODS OF PRODUCING THE SAME
Abstract:
The present disclosure relates to a modified polyester polyol composition useful in the formulation of polyurethane and polyisocyanurate cellular polymers for use in making foam articles with hydrocarbon blowing agents. The modified polyester polyol composition comprises the reaction product of a polyol with an EO/PO block copolymer having a weight average molecular weight from 1,000 to 20,000 g/mol and has a viscosity in the range of 100 to 10,000 centipoise, as determined at 25°C according to the ASTM D-4878 method.
