Abstract: The invention relates to a method for producing a polyurethane foam material, in which (a) polymeric MDI having a content of difunctional MDI of less than 40 wt%, and an aliphatic, halogenated hydrocarbon compound (d1), constructed of 2 to carbon atoms, at least one hydrogen atom and at least one fluorine and/or chlorine atom, wherein the compound (d1) contains at least one carbon-carbon double bond, mixed to an isocyanate component (A), are reacted with a polyol component (b) to form a polyurethane foam material. The invention furthermore relates to a polyurethane foam material obtainable by such a method, and to the use of an isocyanate component (A) for producing polyurethane foam materials.
