Abstract:
A self-sealing elastomer composition, in an inflatable article such as a pneumatic tire (1), such composition comprising, as predominant elastomer, a thermoplastic styrene (TPS) elastomer and an extender oil with a content of between 200 and 700 phe (parts per hundred parts of elastomer by weight). An airtight puncture-resistant laminate (10) that can be used in particular in said inflatable article (1), comprises a puncture-resistant first layer (10a) comprising said self-sealing composition and an airtight second layer (10b), for example based on butyl rubber. An inflatable article comprises such a self-sealing composition or such an airtight puncture-resistant laminate.
