Abstract
Polyol blend compositions are provided containing nonionic ethoxylate propoxylate compounds and aromatic ester polyols, especially phthalate polyester polyols, which blends are miscible with fluorocarbon blowing agents. These blends are suitable for reaction with polyfunctional organic isocyanates in the presence of polymerization catalysts to make cellular polyurethanes and polyisocyanurates.
