Abstract

L’invention concerne une composition de caoutchouc qui comprend un élastomère diénique fortement saturé qui est un copolymère d’éthylène et d’un 1,3-diène qui comprend des unités éthylène qui représentent plus de 50% en moles des unités monomères du copolymère, un système de vulcanisation, une charge renforçante qui contient une silice, un agent de couplage silane et un hydrate d’un sel de thiosulfate inorganique. Une telle composition présente une hystérèse réduite.
