摘要: Pneumatic article such as a pneumatic tyre provided with an anti-puncture layer comprising, self-sealing composition, elastomer composition comprising at least, the predominant elastomer, thermoplastic styrene (known “TPS”), more than 200 phr of extender oil and 20 hydrocarbon-based resin having glass transition temperature greater 0°C. The is advantageously combined airtight layer, for example based on butyl rubber, in order to constitute, article, laminate.
