Abstract: Hydrophilic flame retardant flexible polyurethane foam is prepared by reaction of a polyetherol mixture comprising at least one 2-8 functional polyetherol, based on propylene oxide and/or butylene oxide and ethylene oxide and at least one polyetherol based on propylene oxide and/or butylene oxide and the flame retardant is melamine, optionally mixed with other flame retardants. Hydrophilic flame retardant flexible polyurethane foam (I) is produced by reaction of (A) an optionally modified organic polyisocyanate with (B) a polyetherol mixture and optionally (C) other compounds having isocyanate reactive hydrogen atoms in the presence of (D) water and/or other propellants, (E) catalysts, (F) stabilizers, (G) flame retardants and optionally (H) other additives and processing aids. The polyetherol mixture (B) comprises (B1) at least one 2-8 functional polyetherol, based on propylene oxide and/or butylene oxide and ethylene oxide, whereby the ethylene oxide content (with respect to total alkylene oxide content) is greater than 40 wt.%, having an OH number of 20-800 mgKOH/g and a prim. OH group content of greater than 50 % whereby (B11) contains at least one difunctional polyetherol (B1.1) having an OH number of 20-100 mg KOH/g and (B2) at least one polyetherol based on propylene oxide and/or butylene oxide having an OH number of greater than 30 mg KOH/g and the flame retardant (G) is melamine, optionally mixed with other flame retardants.
