Abstract
A self-sealing elastomer composition that can be used especially as a puncture-resistant layer in an inflatable article, comprising: as predominant elastomer, an unsaturated diene elastomer; a thermoplastic hydrocarbon plasticizer resin with a weight content of between 30 and 90 phr; a liquid plasticizer, the T(glass transition temperature) of which is below −20° C., with a weight content between 0 and 60 phr; and 0 to less than 30 phr of a filler. Also disclosed is an article such as a tire provided with the puncture-resistant layer comprising the self-sealing elastomer composition. The puncture-resistant layer is advantageously combined with an airtight layer, for example based on butyl rubber, so as to form, in the inflatable article, a puncture-resistant airtight laminate.
