PNEUMATIC ARTICLE PROVIDED WITH A SELF-SEALING COMPOSITION

摘要

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