Title
(EN) TREAD WITH HIGH DRAINAGE
(FR) BANDE DE ROULEMENT À DRAINAGE ÉLEVÉ
Abstract
(EN) A tread comprising a plurality of grooves and manufactured using a rubber compound comprising at least one cross-linkable unsaturated chain polymeric base, a filler, a vulcanization system and a wax comprising at least 50% by weight nonacosandiols. At least part of said grooves has a hydrophobic surface structure comprising a plurality of protruding elements.
(FR) L'invention concerne une bande de roulement comprenant une pluralité de rainures et fabriquée à l'aide d'un composé de caoutchouc comprenant au moins une base polymère à chaîne insaturée réticulable, une charge, un système de vulcanisation et une cire comprenant au moins 50 % en poids de nonacosandiols. Au moins une partie desdites rainures a une structure de surface hydrophobe comprenant une pluralité d'éléments en saillie.
