    Abstract: A polyurethane foam, polyisocyanurate foam or polyurea foam is obtainable from the reaction of a mixture comprising A) a compound reactive towards isocyanate (“NCO-reactive compound”); B) a blowing agent selected from the group comprising linear, branched or cyclic C1 to C6 hydrocarbons, linear,branched or cyclic C1 to C6 fluorocarbons, N2, O2, argon and/or CO2, where the blowing agent B) is present in the supercritical or near-critical state; C) a polyisocyanate; D) an amphiphilic isocyanate; and E) optionally a surfactant and F) optionally other auxiliaries and additives. The invention further relates to the production of this polyurethane foam, where the blowing agent is emulsified in the isocyanate component containing amphiphilic isocyanate.
