Abstract: The present invention relates to soft, closed cell polyolefin foams showing a good combination of high temperature resistance and softness as well as a laminate and uses thereof.

Abstract: The invention provides a process for the production of a 5 crosslinked polymer foam, which comprises the following steps: (I) blending a polymer with a blowing agent, (II) forming the blend into a sheet, (III) crosslinking the sheet, and (IV) foaming the sheet, wherein the blowing agent is blended in an amount of 3 to 25 based on the total weight of the polyolefin and the blowing agent, and is composed of (A) 3 to 50% of one or more inorganic carbonates and (B) 50 to 97 of one or more compounds selected from the group consisting of polycarboxylic acids, salts thereof, and derivatives thereof.

Abstract: A decorative sheet arranged on the outside or inside of buildings is composed of a compression-molded core made from one or more core layers. The core contains cellulose fibers or wood fibers, bound to one another by a hot-curing resin. Each core layer is composed of wood fibers or of cellulose fibers having lengths from 0.3 to 30 mm, and is containing pigments or is without pigments. The pigments are uniformly distributed within the core layer, and their proportion by weight is from above 0 to 20% by weight of the mixture made from pigments and from wood fibers or cellulose fibers. The pigments are colorfast, and weathering of the wood fibers or cellulose fibers at the surfaces of the sheet causes the original coloration of the core surfaces to change so that, when dry, the core is covered by a gray-silver patina, but substantially regains its original coloration when wet.
