Abstract

La présente invention concerne des compositions de caoutchouc présentant une résistance au roulement et une adhérence sur sol mouillé améliorées. Ces compositions sont à base d’au moins une matrice élastomère comprenant au moins un copolymère contenant des unités éthylène et des unités 1,3-diène, la fraction molaire des unités éthylène dans le copolymère étant compris dans un domaine allant de plus de 50% à 95%, le copolymère ne contenant pas d’unité d’un 1,3-diène de formule CH2=CR-CH=CH2, le symbole R représentant une chaîne hydrocarbonée ayant 3 à 20 atomes de carbone ; un plastifiant liquide polaire présentant une Tg inférieure à -80°C ; au moins 30 pce de silice ; au moins un agent de couplage de la silice à un élastomère diénique ; et un système de réticulation. L’invention concerne également des articles en caoutchouc comprenant une composition selon l’invention, en particulier des bandages pneumatiques ou non-pneumatiques dont la bande de roulement comprend une composition selon l’invention.
