Title (EN) TYRE FOR VEHICLE WHEELS
(FR) PNEUMATIQUE DESTINÉ À DES ROUES DE VÉHICULE
Abstract:
(EN) The present invention relates to a tyre for vehicle wheels comprising at least one external structural element comprising at least one external structural element comprising a crosslinked elastomeric material obtained by crosslinking a crosslinkable elastomeric composition comprising (i) at least one diene elastomeric polymer, and (ii) a system for protection against ozone substantially free of polymeric static protective agents which essentially consists of at least one phenolic antioxidant in an amount substantially equal to or higher than 3 phr.
(FR) La présente invention concerne un pneumatique destiné à des roues de véhicule comprenant au moins un élément structural externe comprenant un matériau élastomère réticulé obtenu par réticulation d'une composition élastomère réticulable comprenant (i) au moins un polymère élastomère diénique et (ii) un système de protection contre l'ozone sensiblement exempt d'agents protecteurs statiques polymères qui consiste essentiellement en au moins un antioxydant phénolique en une quantité sensiblement égale ou supérieure à 3 pce.
