Abstract
A resin blend composition is provided containing a polyol, an ethoxylate propoxylate surfactant initiated by a short chain compound, and a hydrocarbon blowing agent. The solubility and/or compatibility of the hydrocarbon carbon blowing agent in the polyol is increased and the phase stability of the resin blend composition is improved by the ethoxylate propoxylate surfactant. The resin blend is suitable for reaction with polyfunctional organic isocyanates to make cellular polyurethane and polyisocyanurate foams.
