| 发明名称 | Self-sealing elastomer composition | ||
| 摘要 | Self-sealing elastomer composition that can in particular be used as puncture-resistant layer in an inflatable article, comprising at least 30 phr of a saturated thermoplastic styrene elastomer, at most 70 phr of an unsaturated thermoplastic styrene elastomer and more than 200 phr of an oil extender. Inflatable article, such as a tire, provided with a puncture-resistant layer comprising, as self-sealing composition, an elastomer composition according to the invention. Advantageously, the puncture-resistant layer is combined with an airtight layer, for example based on butyl rubber, so as to constitute, in the inflatable article, a puncture-resistant airtight laminate. | ||

| 主权项 | 1. A self-sealing thermoplastic elastomer composition that can be used in particular as a puncture-resistant layer in an inflatable article, comprising at least the following (in which phr denotes parts by weight per hundred parts of rubber): at least 30 phr of a saturated thermoplastic styrene elastomer; from more than 0 phr to 70 phi of an unsaturated TPS elastomer; and more than 200 phr of an oil extender for said elastomers. | ||
