Abstract (en)
[origin: WO2019011956A1] The invention relates to flame-retardant flexible polyurethane foams with phospazene and to methods for producing PUR flexible foams by reacting a component A containing: A1, an isocyanate-reactive component, A2, a propellant containing water, A3, optionally auxiliary agents and additives, and A4, a flame retardant, with B, an isocyanate component. The invention is characterized in that the flame retardant A4 contains a phosphazene according to the formula (I): [PmNmXk] (I), where X independently of one another represents O-aryl or NR-aryl, at least one aryl group is substituted, X can represent a bridge, R is selected from the group of H, C1-C4 alkyl, and aryl, and m represents a number from 1 to 5, particularly preferably 3 or 4, k depends on m and represents a number from 0 to 2m, and the phosphazene does not have any groups which are reactive towards isocyanates.
