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 comprenant de 45% à 100% en poids, de triester d’acide gras insaturé de glycérol ; plus de 30 pce de charge renforçante 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.
