ELASTOMERIC COMPOSITIONS COMPRISING NATURAL RUBBERS FROM GUAYULE FOR TYRE COMPONENTS AND TYRES COMPRISING THE SAME

摘要

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.
