Abstract: The invention concerns a wiper blade (1) for a windscreen wiper frame, at feast a portion of said blade (1) comprising a material made from natural rubber and at least one additive, characterised in that said additive is at least a bio-sourced plasticiser and in that said blade comprises, as the only rubber, said natural rubber in the vulcanised state, said vulcanised rubber being obtained by vulcanising a non-functionalised natural rubber. The invention also concerns a windscreen wiper frame comprising such a wiper blade and a wiper system comprising such a windscreen wiper frame.

Abstract: A formulation for the preparation of a wiping blade element for a vehicle windscreen wiper blade is disclosed. The formulation has an elastomer material based on chloroprene rubber in which plasticizing additives are incorporated, where the plasticizing additives include a combination of at least a first additive, the pour point of which is less than ?50° C., and at least a second additive, the pour point of which is greater than ?50° C. The first additive is octyl sebacate in a proportion of 4 phr and the second is a naphthalic oil plasticizer or a C18-C30 tricarboxylic ester in a proportion of 10 phr.
