Production of flame-resistant flexible polyurethane foams

摘要

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 two reactive hydrogen atoms and c) if desired, low molecular weight chain extenders in the presence of d) 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.
