Abstract: A polyisocyanate component used for the production of flexible polyurethane foam with water as blowing agent comprises a mixture of a prepolymer obtained by reacting excess MDI with non-polar polyether-polyol(s) and a prepolymer obtained by reacting excess MDI with polar polyether-polyol(s). A method for the production of flexible polyurethane foam by reacting (a) polyisocyanates with (b) compounds with at least two NCO-reactive hydrogens in presence of (c) water as blowing agent, in which component (a) is a mixture of (ai) a prepolymer obtained by reacting MDI with less than the stoichiometric amount of non-polar polyether-polyol(s) and (aii) a prepolymer obtained by reacting MDI with less than the stoichiometric amount of polar polyether-polyol(s). An independent claim is also included for flexible polyurethane foam obtained by this method.
