| abstract |
The invention relates to a laminate for a pneumatic object, comprising at least three different stacked layers: an inflation-gas-tight layer consisting of a composition comprising at least one diene elastomer and at least one crosslinking system, the diene elastomer content being within a range from 50 to 100 phr; a coupling layer consisting of a composition comprising at least one styrene thermoplastic elastomer, at least one polyolefin having a number average molar mass Mn of between 10000 g/mol and 550000 g/mol and at least 140 phr of an extender oil having a number average mass Mn less than or equal to 5000 g/mol; a self-sealing layer consisting of a composition comprising at least one styrene thermoplastic elastomer and at least 140 phr of an extender oil, the styrene thermoplastic elastomer content being within a range from 50 to 100 phr, the aforementioned coupling layer being disposed between the inflation-gas-tight layer and the self-sealing layer. The invention also relates to the use of said laminate as an inner wall for a tyre and to a tyre comprising at least one laminate as defined above. |
