Abstract: A bearing bush includes at least one sealing element and one bearing element. The sealing element is provided with at least one sealing lip. The bearing element is substantially tubular. The bearing element includes a plurality of protrusions extending in the axial direction on the outer circumference. The inner diameter of the bearing element is larger in the sections corresponding to the protrusions than in the remaining sections.

Abstract: A composition for shielding against electromagnetic radiation includes: a) at least one conductive filler; and b) a polymer matrix including at least one polyurethane containing urea group. The at least one polyurethane containing urea group has a degree of branching from 0 to 20%. In an embodiment, the polymer matrix comprises at least one non-conductive matrix polymer which is different from the at least one polyurethane containing urea group.

Abstract: A method produces a substrate shielded from electromagnetic radiation. The method includes i) providing a first polymer material (a) or a precursor thereof containing at least one conductive filler and at least a second polymer material (b) or precursor thereof; ii) obtaining a substrate by subjecting the first polymer material (a) or the precursor thereof and the second polymer material (b) or the precursor thereof to shaping with material bonding of the first polymer material (a) and the second polymer material (b), and polymerizing, if present, the precursors; and iii) at least partially surrounding an electronic component with the substrate obtained in step ii). A polymer component of the first polymer material (a) includes a thermoplastic elastomer or at least one thermoplastic elastomer, selected from the group consisting of, e.g., thermoplastic polyamide elastomers, thermoplastic copolyester elastomers, thermoplastic olefin-based elastomers, thermoplastic styrene block copolymers, polyether block amides, and mixtures thereof.

Abstract: A sealing arrangement includes: a first machine element and a second machine element, each made of an electrically-conductive material; and a seal. The first and second machine elements are sealed against one another by the seal. At least one of the machine elements is made of an electrically-conductive plastic which is at least partially covered by an electrically-insulating, injection-molded skin as a result of production. The seal has an electrically-conductive support body. The support body has at least one substantially mandrel-shaped projection comprising an electrically-conductive material which is arranged on a side of the support body facing the injection-molded skin and completely penetrates the injection-molded skin.
