Abstract
A crosslinkable elastomeric composition has at least one vulcanized rubber in a subdivided form surface treated with at least one silane coupling agent, at least one diene elastomeric polymer and at least one sulfur-based vulcanizing agent. The crosslinkable elastomeric composition is advantageously used in the production of crosslinked manufactured products, in particular, in the production of tires for vehicle wheels.

A crosslinkable elastomeric composition comprising:
- at least one vulcanized rubber in a subdivided form surface treated with at least one silane coupling agent;
- at least one diene elastomeric polymer;
- and
- at least one sulfur-based vulcanizing agent.
A tire for a vehicle wheel, comprising at least one structural element obtained by crosslinking a crosslinkable elastomeric composition comprising:
- at least one vulcanized rubber in a subdivided form surface treated with at least one silane coupling agent;
- at least one diene elastomeric polymer;
- and
- at least one sulfur-based vulcanizing agent.
A process for producing a crosslinkable elastomeric composition comprising the following steps:
- (a) surface treating at least one vulcanized rubber in a subdivided form with at least one silane coupling agent;
- (b) mixing the surface treated vulcanized rubber in a subdivided form obtained in step (a) with at least one diene elastomeric polymer;
- and
- (c) adding to the elastomeric composition obtained in step (b) at least one sulfur-based vulcanizing agent.
