Abstract: The present invention relates to compositions for elastomeric compounds for tyres, in particular for tyre treads, comprising particular reversible cross-linking agents, tyre components and tyres for vehicle wheels which comprise them. The present elastomeric compounds, due to their particular hysteretic behaviour, allow manufacturing tyres characterised by a lower rolling resistance during moderate driving and at the same time greater resistance to tearing and road grip during sports driving.

Abstract: The present invention relates to new elastomeric materials for the production of tyres for vehicle wheels with good mechanical properties, in particular high moduli associated with low hysteresis values, including new reinforcement materials. Said reinforcement materials are obtainable by derivatising silica—in-situ during the mixing of the elastomeric composition, or previously—with special silanising agents (A) and silsesquioxanes (B), both substituted with reactive alkenyl functionalities.

Abstract: The present invention regards a solid master elastomeric composition (masterbatch, MB) comprising silicate fibres with needle-shaped morphology of nanometric size, characterised by high fibre content and uniformity, a process advantageous for the preparation thereof and its use in manufacturing tyres for vehicles. Advantageously the present elastomeric composition allows minimising the drawbacks associated with the handling of the powdery fibres in the manufacturing of compounds for tyres, without altering the final performances thereof.

Abstract: A soundproof tyre and a process for the production thereof. The tyre includes particular polyolefin sound absorbent foams that provide damping for noise generated in a cavity of the tyre, together with resistance to hydrolysis, poor water absorption and an unexpected thermal and mechanical stability in use conditions. The sound absorbent material is applied on at least a portion of a radially inner surface of the tyre. The portion of the radially inner surface includes an impermeable elastomeric material layer. The sound absorbent material includes a foamed polyolefin material with closed macrocells having an average size of at least 1.5 mm according to ASTM D357 6.
