摘要： Airtight and puncture-resistant multilayer elastomer laminate that can be used in particular in an inflatable article, such as a pneumatic tire for a vehicle, comprising at least the following three layers (phr signifying parts by weight per hundred parts of rubber (elastomer) in each composition considered): as an airtight first layer, a first elastomer composition comprising at least 50 phr of a diene elastomer; as a puncture-resistant second layer, a self-sealing second elastomer composition comprising at least 50 phr of a saturated thermoplastic stirene elastomer and more than 200 phr of an extender oil; as an adhesive third layer or interphase between the above two layers, a third composition comprising at least 30 phr of an unsaturated thermoplastic stirene elastomer.

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 stirene elastomer, at most 70 phr of an unsaturated thermoplastic stirene 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.
