| abstract |
The present invention relates to a rubber composition made of at least one diene elastomer, a reinforcing filler, and a cross-linking system, characterised in that said composition comprises at least 10 to 150 pce of a lamellar filler and 0.01 to 0.3 pce of a metal salt. Said composition has good processability and mechanical properties, as well as improved properties of imperviousness to oxygen across a wide range of temperatures, from ambient temperatures when the tyre is stopped until temperatures of the tyre while running. According to a preferred embodiment of the invention, the previously described rubber composition can be used in the tyre as a protective elastomer layer in at least one portion of the tyre. |
