Title (EN) WIPER BLADE, PRODUCTION METHOD AND WIPER FRAME DEVICE CONTAINING NATURAL RUBBER AND POLYBUTADIENE
(FR) LAME D'ESSUIE-GLACE, PROCEDE DE PREPARATION ET DISPOSITIF DE BALAI D'ESSUIE GLACE A BASE DE CAOUTCHOUC NATUREL ET POLYBUTADIENE
Abstract:
(EN) The invention relates to a wiper blade, in particular a wiper blade comprising a rubber structure, to a method for producing such a blade, and to a wiper frame device. According to the invention, the rubber structure is formed from an elastomer matrix comprising: between 25 and 60 phr of natural rubber; and between 40 phr and 75 phr of polybutadiene.
(FR) L'invention concerne une lame d'essuie-glace et notamment une lame d'essuie-glace comprenant une structure de caoutchouc, un procédé de préparation d'une telle lame,ainsi qu'un dispositif de balai d'essuie-glace. Selon l 'invention la structure de caoutchouc est formée d'une matrice élastomérique comprenant : de 25 à 60pce de caoutchouc naturel; et de 40 pce à 75 pce de polybutadiène.
