    • 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).

    • 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).
