Abstract

A flexible polyurethane foam comprises the reaction product of an isocyanate component and an isocyanate-reactive component in the presence of a blowing agent. The isocyanate component comprises a polymeric diphenylmethane diisocyanate component and a monomeric diphenylmethane diisocyanate component. The monomeric diphenylmethane diisocyanate component comprises 2,4′-diphenylmethane diisocyanate and 4,4′-diphenylmethane diisocyanate. The isocyanate-reactive component comprises a polyether polyol having a molecular weight of from about 700 to about 20,000 and a plurality of terminal caps which are substantially free of ethylene oxide groups. The flexible polyurethane foam is substantially free of supplemental flame retardant additives and exhibits flame retardance under flammability tests according to California Technical Bulletin 117 regulations.
