摘要： The present invention relates to new vulcanisable elastomeric compositions for components of tyres, comprising modified silicate fibres as fillers. The silicate fibres are modified according to the process with controlled pH of the invention. In addition, the invention regards components of tyres, comprising elastomeric materials obtainable by vulcanisation of said compositions, and tyres for vehicles comprising one or more of said components. The vulcanised elastomeric materials according to the invention are characterised by good static and dynamic mechanical properties, in particular by particularly low hysteresis. Advantageously the tyres of the invention comprising one or more of said components have a limited rolling resistance.

摘要： 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.

摘要： 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.
