Abstract: The invention relates to a wiping rubber for wiper blades in windshield wipers, comprising a profile body formed of an elastomer or rubber material, at least partially having a surface coating. The surface coating (22) comprises carbon fibers (24).

Abstract: The invention relates to a wiper blade element (10) for a wiper blade, for example of a motor vehicle. In order to minimize the running noise, said wiper blade element (10) comprises an elastomer material (A) which comprises a polymer blend from at least one ethylene-propylene-(diene)-rubber and at least one polymer, selected from the group consisting of polynorbornene, trans-polyoctenamer, polyisobutylene, chloroprene rubber, butyl rubber, chlorobutyl rubber, bromobutyl rubber and mixtures thereof. In the polymer blend, the weight ratio of ethylene-propylene-(diene) rubber and/or ethylene-propylene rubber to the at least one polymer is in a range of 40:60-95:5. The invention also relates to said type of elastomer material (A) and a wiper blade equipped with said type of wiper blade element (10).

In order to minimize the running noise, said wiper blade element (10) comprises an elastomer material (A) which comprises a polymer blend from at least one ethylene-propylene-diene rubber (EPDM) and/or at least one ethylene-propylene-rubber (EPM) and at least one ethylene-vinyl-acetate copolymer (EVM), said polymer blend containing at least one ethylene-vinyl acetate-copolymer having a vinyl acetate-content in the region of ?45 wt.-% to ?85 wt.-%, with respect to the total weight of the ethylene-vinyl acetate-copolymer. The invention also relates to said type of elastomer material (A) and to a wiper blade equipped with said type of wiper blade element (10).

Abstract: The present invention relates to a coating for elastomeric linear profiles, where the coating comprises solid lubricant embedded into a polymeric matrix. It also relates to a wiper blade for windscreen wipers, comprising this type of coating, and also to a process for the production of an elastomeric linear profile coated according to the invention. The polymeric matrix with embedded solid lubricant is obtained by polymerizing, in the absence of polymeric binders, a mixture comprising the solid lubricant and low-molecular-weight crosslinking agent. In one embodiment, the matrix is obtained from the thermal polymerization of the low-molecular-weight crosslinking agent hexamethoxymethylmelamine. Examples of solid lubricants are graphite and HDPE.
