Abstract: PVC-free decorative surface covering comprising a reinforced layer, said layer comprising a carrier impregnated with a PVC-free paste, said paste comprising from 5 to 50% by weight of a PVC-free polymer blend, from 45 to 90% by weight of one or more fillers and from 0.5 to 12% by weight of one or more lubricants. The PVC-free decorative surface coverings are prepared by a calendering process.

Abstract: The present invention relates to a multilayer surface coating, including a PVC layer including inorganic fillers, said coating including a barrier layer including polyvinyl alcohol and a silane compound, said silane compound including at least one amine function.

Abstract: A method for manufacturing a multilayer surface coating including a PVC expanded surface layer is provided. The method includes the step of applying an aqueous composition including polyvinyl alcohol to the bottom portion of said supporting layer prior to the step of expanding said supporting layer.

Abstract: The invention relates to a lining method and a lining installation for the production of multi-layer products which are used, for example, to produce floor or wall coverings or interior trim for passenger transport vehicles, such as cars, railroad cars, ship cabins and aircraft cockpits.

Abstract: The invention relates to multi-layer products comprising a polymer substrate (1), a wearing layer (2) which is made from an ionemer-type polymer and an intermediary layer (3) which is made from an olefin polymer containing a metallocene. The invention also relates to a method of producing one such product and to the use of said multilayer products for the production of flooring.

Abstract: The invention concerns a process for preparing powdery ionomers by neutralizing a powdery precursor using a neutralizing agent. A particular feature of the invention is that the precursor is used in a powder form and a concentrated aqueous solution of neutralizing agent is rapidly mixed with the precursor, and that the neutralized ionomer essentially retains the dry powder form and size of a precursor while having a water content of about 10%. The resulting product can be used as a wear layer for producing ground and wall coverings, either by powder deposition process or by extension to form a film, which is applied in a hot state to a support.
