Abstract (en)
[origin: WO2020141070A1] The present invention relates to a method for producing a wiper blade element (10) for a wiper blade and/or a wiper blade having a wiper blade element (10), in particular for a windscreen wiper. In order to provide simple and economical wiper blade elements and wiper blades having excellent properties, in particular having high wiping quality, high abrasion resistance, a high degree of friction reduction and running noise reduction and a long service life, in said method a particle layer (12) is applied to an elastomer substrate (11), the elastomer substrate (11) is vulcanised with the particle layer (12) deposited thereon, and, after vulcanisation, a friction-reducing material (13) is applied to the particle layer (12). The invention further relates to a wiper blade element and wiper blade produced in such a way.
