Title (EN) TYRE HAVING A COMPOSITION COMPRISING AN ETHYLENE-RICH ELASTOMER, A PEROXIDE AND A ZINC ACRYLATE
(FR) PNEUMATIQUE MUNI D'UNE COMPOSITION COMPRENANT UN ELASTOMERE RICHE EN ETHYLENE, UN PEROXYDE ET UN ACRYLATE DE ZINC
Abstract:
(EN) The invention relates to a tyre having improved wear resistance, rolling resistance and cohesion, comprising a rubber composition including at least: an elastomer matrix containing mainly a statistical copolymer comprising ethylene units and conjugated diene units, the mole fraction of the ethylene units in the copolymer being in the range from 50% to 95%; a peroxide; and a derivative of zinc diacrylate in the form of a specific zinc salt, the levels of zinc diacrylate derivative and peroxide in the composition being such that the peroxide to zinc diacrylate derivative content ratio is greater than or equal to 0.08. The composition comprises from 5 to less than 65 phr reinforcing filler, and the filler to zinc diacrylate derivative content ratio is greater than or equal to 1.25.
(FR) L'invention concerne un pneumatique à résistance à l'usure, résistance au roulement et cohésion améliorées, comprenant une composition de caoutchouc à base d'au moinsune matrice élastomérique comprenant majoritairement un copolymère statistique comprenant des unités éthylène et des unités diéniques conjuguées, la fraction molaire des unités éthylène dans le copolymère étant compris dans un domaine allant de 50% à 95%; un peroxyde; et un dérivé du diacrylate de zinc sous la forme d'un sel de zinc spécifique; composition dans laquelle les taux de dérivé de diacrylate de zinc et de peroxyde étant tels que le rapport du taux de peroxyde sur le taux de dérivé de diacrylate de zinc est supérieur ou égal à 0,08; ladite composition comprenant de 5 à moins de 65 pcede charge renforçante; le rapport du taux de charge sur le tauxde dérivé de diacrylate de zinc étant supérieurou égal à 1,25.
