Abstract: The present invention concerns a process for producing a thermoformable porous web using a mixture of cellulosic fibers and one or more thermoplastic materials, particularly by foam forming said mixture into a composite foam, and applying the foam into one or more layers on a support to obtain a porous pre-form web. The thus produced porous composite web can be further processed by compression molding to give a rigid high-strength composite structure, which is suitable for use in producing, e.g. panels or plates, packages or hygiene products, insulators or filters, or printed intelligence, electronics or microcellulose products.

Abstract: The invention relates to an electrically conductive elastomer mixture and to a method. The mixture comprises a thermoplastic styrene elastomer and, as an electrically conductive filler, metal-containing particles. The mixture further comprises a polymer which is an acid-grafted, acid-anhydride-grafted or acid-copolymer and which forms an IPN (Interpenetrating Polymer Network) network structure with the styrene elastomer.
