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.

Cold flexible polyurethane formulation

The invention relates to a method for the production of composite elements comprising at least one outer layer a) and a layer b) firmly bonded to it, an adhesion promoter c) being applied between the outer layer a) and the layer b) firmly bonded to it, the outer layer a) being continuously moved and the adhesion promoter c) and the layer b) firmly bonded to it or the starting materials thereof being applied in succession to the outer layer, the application of the adhesion promoter c) being effected by means of a rotating disk which is mounted horizontally or with a slight deviation from the horizontal of up to 15&#xb0;, wherein the rotating disk is provided with teeth on the edge.
