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).
