Title (EN) TIRE SIDEWALL COMPOSITION
(FR) COMPOSITION D'EPAULEMENT DE PNEU
Abstract:
(EN) Tires having a sidewall composed of a composition formed by curing a blend comprised of (A) high molecular weight (6 x 105 M^¨B7u) ethylene/alphaolefin/nonconjugated polyene terpolymer; (B) a higly unsaturated rubber; and (C) a curative system comprised of sulfur and/or a sulfur-donor compound, an organic (hydro)peroxide curative and a sulfur cure accelerator exhibit desirable reduced internal heat buildup and improved adhesion to adjacent rubber carcass and tread portions of the tire.
(FR) Pneus dont la composition de l'épaulement est formée par vulcanisation d'un mélange comprenant (A) un terpolymère d'éthylène/alphaoléfine/polyène non conjugué de masse moléculaire élevée (6 x 105 M^¨B7u); (B) un caoutchouc hautement saturé; et (c) un système vulcanisant composé de soufre et/ou d'un composé donneur de soufre, un agent vulcanisant (hydro) peroxyde organique ainsi qu'un accélérateur de vulcanisation de soufre, présentant une accumulation de chaleur interne désirable réduite et une adhérence améliorée à des parties de carcasse et de bande de roulement adjacentes en caoutchouc du pneu.
