Abstract: Described herein are processes for producing cold-flexible polyurethane insulation, in which (a) polyisocyanates are mixed with (b) compounds having groups which are reactive to isocyanates, (c) blowing agents, (d) catalysts, (e) plasticizers and optionally (f) further additives to give a reaction mixture and the mixture is applied to a surface and cured to form insulation. Also described herein is a polyurethane insulation obtainable by a process described herein.

Abstract: Described herein are processes for producing a polyurethane foam by mixing the following: (a) polymeric MDI with less than 40% by weight content of difunctional MDI and an aliphatic halogenated hydrocarbon compound (d1) composed of 2 to 5 carbon atoms and of at least one hydrogen atom and of at least one fluorine and/or chlorine atom, where the compound (d1) includes at least one carbon-carbon double bond, to give an isocyanate component (A), and reacting with a polyol component (b) to give the polyurethane foam. Also described herein is a polyurethane foam obtainable by said process.
