Abstract: A wiper rubber (10) for a wiper blade, especially for a windshield wiper, with an elastomer material comprising a polymer blend composed of at least one ethylene-propylene-diene rubber and/or at least one ethylene-propylene rubber, and at least one ethylene-vinyl acetate copolymer is disclosed. In order to provide a wiper rubber that has improved wiping quality and improved running properties, especially reduced or zero running noise, such as humming, whistling, squeaking, smacking, turnover noises, et cetera, both at moderate and especially at cold outside temperature, and especially also over a broad frequency range customary in wiper operation, the at least one ethylene-vinyl acetate copolymer, based on the total weight of the at least one ethylene-vinyl acetate copolymer, comprises a vinyl acetate content within a range from ?40% by weight to ?90% by weight, where the polymer blend, based on the total weight of the polymers in the polymer blend, comprises ?0.

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 (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 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).

Abstract: The invention relates to a wiper rubber for windshield wipers, which contains at least one rubber component that is cured by vulcanization, the material of the wiper rubber containing, at least in the unvulcanized state, a combination of a cross-linking agent with sulfur and/or with a sulfur donor.

Abstract: A rubber material of a wiper blade for windshield wipers is described, which comprises a first rubber component of a first polarity and a second rubber component of a second greater polarity. To equalize the first and second polarities, the first rubber component is at least partially replaced by a chemically functionalized derivative.

Abstract: A silicone-polymer-modified vulcanized-rubber composition based on unvulcanized rubber, characterized in that the composition can be produced by co-vulcanization from the following components: A1) at least one vinyl-reactive polysiloxane component, and/or A2) at least one mercapto-reactive polysiloxane component, and B) at least one unsaturated vulcanizable unvulcanized-rubber component, and to a process for the production of said silicone-polymer-modified vulcanized-rubber composition based on unvulcanized rubber, and also to a windshield-wiper blade encompassing a silicone-polymer-modified vulcanized-rubber composition based on unvulcanized rubber.
