Abstract: The present invention is directed to the use of a composite comprising a layer (L1) selected from the group of polyurethane layers, polyisocyanurat layers and polyurea layers as a landfill liner as well as a process for preparing a composite landfill liner comprising a layer (L1) selected from the group of polyurethane layers, polyisocyanurat layers and polyurea layers, the process comprising the step of applying a reaction mixture which is suitable to form a product selected from the group of polyurethane, polyisocyanurat and polyurea products onto a surface. Furthermore, the present invention is directed to a composit comprising a layer (L1) selected from the group of polyurethane layers, polyisocyanurat layers and polyurea layers, a primer layer on one surface of layer (L1), and a protective layer (L2) selected from the group of mortar layers or elastomer layers on the surface of the primer layer.In particular, the present invention is directed to the use of a composite comprising a polyurethane foam layer (L1) as a landfill liner, wherein the layer (L1) comprises a spray product as well as a preparing a composite landfill liner comprising a polyurethane foam layer (L1), the process comprising the step of applying a reaction mixture which is suitable to form a polyurethane foam onto a surface. Finally, the present invention is directed to a composite comprising a polyurethane foam layer (L1), a primer layer on one surface of layer (L1), and a protective layer (L2) selected from the group of mortar layers or elastomer layers on the surface of the primer layer.

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.
