Abstract
Advantageous rigid polyurethane foam properties (e.g. compressive strength) can be improved and the proportions of polymerization catalyst and/or surfactant needed to provide a given level of such properties can be lowered by preparing such foams from compositions comprising, in addition to the conventional foam-forming reactants including polyisocyanate and polyol, from about 3% to about 10%, based on the weight of the polyol, of a plasticizer selected from essentially halogen-free phosphates and carboxylates containing at least one aryl radical, e.g. isodecyl diphenyl phosphate or butyl benzyl phthalate.
