Flame-resistant flexible polyurethane foams are produced by reacting a) organic and/or modified organic polyisocyanates, b) relatively high molecular weight compounds containing at least twa reactive hydrogen atoms and c) if desired, low molecular weight chain exteders in the presence of catalysts, e) blowing agents f) flame retardants, and, if desired g) auxiliaries and/or additives, where the flame retardants f) used are melamine in combination with at least one anionic dispersant. Isocyanate: MDI prepolymer NCO cvrltent 24 - 28% based on MDI |
