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.

Abstract: A method of producing a porous plastic film, and a porous plastic film. The plastic film is prepared from a raw material blend comprising a polymer-containing basic material and an additive. Pores are generated in the film by stretching a film preform. The additive comprises a POS(S) chemical.

Abstract: A method of preparing an electrically conductive polymer blend, and an electrically conductive polymer blend includes steps of selecting at least two polymeric materials that are substantially immiscible together, mixing the polymeric materials into a blend so that at least one of the polymeric materials forms a continuous three-dimensional phase through the entire blend, and mixing an electrically conductive filler into the blend. The difference in surface tension between the polymeric material forming the continuous three-dimensional phase and the other polymeric materials forming the blend is at least 2 mN/m.

Abstract: An electrically conductive thermoplastic elastomer composite comprising an elastomer matrix and particles coated with metal as an electrically conductive filler. The electrically conductive particles are at least partly coated with a self-assembled monomolecular layer. Alternatively, the coating may comprise molecular wires that settle between the self-assembled molecules. The resistivity of the thermoplastic elastomer of the invention is low and does not substantially increase by the action of compression.

Abstract: A planar porous composite structure including a plurality of regular textile planar layers formed of continuous yarns. The layers are placed on top of each other to form a structure having two dimensions at right angles to each other and a third dimension perpendicular to them and defining a plane having a direction along the two dimensions. A plurality of openings extends through the layers. Each opening is defined by portions of the continuous yarns extending substantially in the direction of the plane and existing in the regular textile planar layers to make the planar layers regular in structure prior to placing them on top of each other. A plurality of passages extends entirely through the structure in a direction substantially perpendicular to the plane of the structure.
