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 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.
