The present invention relates to a method for producing flexible polyurethane foams based on polyoxymethylene-polyoxyalkylene block copolymers. The invention also relates to the use of the flexible polyurethane foams thus produced and their use for producing furniture upholstery, textile inlays, mattresses, automobile seats, headrests, armrests, sponges, foam sheets for use in automobile parts such as roof linings, door panel upholstery, seat covers and technical components. The invention finally relates to a two-component system for producing flexible polyurethane foams.

Flexible polyurethane foams based on polyoxymethylene-polyoxyalkylene block copolymers

The invention relates to flame-retardant flexible polyurethane foams with phosphazene 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): [PNX] (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.
