Title
(EN) TIRE WITH A TREAD COMPRISING AN SNBR ELASTOMER
(FR) PNEUMATIQUE DONT LA BANDE DE ROULEMENT COMPORTE UN ELASTOMERE SNBR
Abstract
(EN)
The present invention relates to a tire comprising a tread including a rubber composition comprising at least: - for the first diene elastomer, 5 to 25 pce of a butadiene-acrylonitrile-styrene (SNBR) terpolymer having a nitrile monomer content of 4 to 18 wt %; - a second diene elastomer other than SNBR; - a reinforcing filler; - a liquid plasticizer, the glass transition temperature of which is less than -20°C. The invention makes it possible to improve the rolling resistance and the grip on wet ground properties of tire treads.
(FR)
La présente invention concerne un pneumatique comportant une bande de roulement comprenant une composition de caoutchouc comportant au moins : - à titre de premier élastomère diénique, entre 5 et 25 pce d'un terpolymère de styrène- nitrile-butadiène (SNBR) ayant une teneur en monomère nitrile entre 4 et 18 % en poids; - un second élastomère diénique autre que SNBR; - une charge renforçante; - un plastifiant liquide dont la température de transition vitreuse est inférieure à -20°C. L'invention permet d'améliorer les propriétés de résistance au roulement et d'adhérence sur sol mouillé des bandes de roulement de pneumatiques.
