Date Mar. 7, 1996A process for imparting flame retardancy to a polyurethane foam comprising the step of incorporating in said polyurethane foam 0.5-50.0 php of at least one flame-retardant phosphate ester is disclosed. Also disclosed is a flame-retardant polyurethane foam composition which comprises a polyurethane foam and 0.5-50.0 php of at least one flame-retardant phosphate ester, as well as the use of a flame-retardant phosphate ester to impart flame retardancy to a polyurethane foam. An example of such a phosphate ester is resorcinol bis(diphenyl phosphate). These flame retardants have the advantage that they reduce fogging caused by evaporation of volatile components from polyurethane foam compositions.
