Title (EN) ELASTOMERIC COMPOSITIONS COMPRISING NATURAL RUBBERS FROM GUAYULE FOR TYRE COMPONENTS AND TYRES COMPRISING THE SAME
(FR) COMPOSITIONS ÉLASTOMÈRES COMPRENANT DES CAOUTCHOUCS NATURELS PROVENANT DE GUAYULE POUR DES COMPOSANTS DE PNEU ET PNEUS LES COMPRENANT
Abstract:
(EN) The present invention relates to new elastomeric compositions for tyres, preferably for high and ultra-high performance (HP and UHP) tyres. These tires are characterised by excellent handling and grip on both wet and dry asphalt, even at high temperatures that are reached in sporty driving or in extreme conditions. The compositions of the invention incorporate natural rubbers and resins from particular Guayule, at least partially replacing those synthetic rubbers and resins of fossil origin typically used and allow producing particularly performing tyres with a lower environmental impact.
(FR) La présente invention concerne des compositions élastomères nouvelles pour pneus, de préférence pour des pneus à hautes et ultra hautes performances (HP et UHP). Ces pneus sont caractérisés par une excellente tenue de route et une excellente adhérence à la fois sur l'asphalte humide et l'asphalte sec, même à des températures élevées qui sont atteintes en conduite sportive ou dans des conditions extrêmes. Les compositions selon l'invention contiennent des caoutchoucs naturels et des résines provenant notamment du guayule, remplaçant au moins partiellement les caoutchoucs synthétiques et les résines d'origine fossile habituellement utilisés et permettent de produire des pneus particulièrement performants ayant un impact environnemental plus faible.
