Abstract (en)

[origin: WO2012084821A1] Reinforced rubber composition based at least (a) on an elastomer matrix comprising natural rubber as majority diene elastomer, (b) on a reinforcing filler comprising carbon black according to a weight fraction of more than 50% relative to the total weight of the filler, and (c) on a compound belonging to the hydrazide or hydrazone families or to the amine family, characterized in that the carbon black is dispersed in the elastomer matrix with a Z score greater than or equal to 80. This rubber composition is intended, for example, for the manufacture of a semi-finished rubber product intended for a motor vehicle tyre.
