Title
(EN) TYRE PROVIDED WITH AN OUTER SIDEWALL COMPRISING ONE OR MORE THERMOPLASTIC ELASTOMERS AND ONE OR MORE SYNTHETIC DIENE ELASTOMERS
(FR) PNEUMATIQUE POURVU D'UN FLANC EXTERNE COMPORTANT UN OU PLUSIEURS ELASTOMERES THERMOPLASTIQUES ET UN OU PLUSIEURS ELASTOMERES DIENIQUES SYNTHETIQUES
Abstract
(EN)
The invention relates to a tyre provided with an outer sidewall, said outer sidewall comprising at least one composition based at least on: an elastomer matrix comprising at least one diene elastomer selected from the group consisting of butadiene polymers having a glass transition temperature of less than or equal to -50°C, and a thermoplastic elastomer comprising at least one elastomer block and at least one thermoplastic block, wherein said thermoplastic elastomer does not contain a polyisobutylene block; a cross-linking system; and a reinforcing filler comprising a carbon black, referred to as first carbon black, having a BET specific surface area of less than or equal to 35 m²/g, and a carbon black, referred to as second carbon black, having a BET specific surface area greater than or equal to 35 m²/g.
(FR)
L'invention concerne un pneumatique pourvu d'un flanc externe, ledit flanc externe comprenant au moins une composition à base d'au moins une matrice élastomérique comprenant au moins un élastomère diénique choisi dans le groupe constitué par les polymères butadiéniques ayant une température de transition vitreuse inférieure ou égale à -50°C, et un élastomère thermoplastique comprenant au moins un bloc élastomère et au moins un bloc thermoplastique, l'élastomère thermoplastique ne comprenant pas de bloc polyisobutylène; un système de réticulation; et une charge renforçante comprenant un noir de carbone présentant une surface spécifique BET inférieure ou égale à 35 m²/g, dit premier noir de carbone, et un noir de carbone présentant une surface spécifique BET supérieure ou égale à 35 m²/g, dit deuxième noir de carbone.
