    摘要： A self-sealing elastomer composition, in an inflatable article such as a pneumatic tire (1), such composition comprising, as predominant elastomer, a thermoplastic styrene (TPS) elastomer and an extender oil with a content of between 200 and 700 phe (parts per hundred parts of elastomer by weight). An airtight puncture-resistant laminate (10) that can be used in particular in said inflatable article (1), comprises a puncture-resistant first layer (10a) comprising said self-sealing composition and an airtight second layer (10b), for example based on butyl rubber. An inflatable article comprises such a self-sealing composition or such an airtight puncture-resistant laminate.

    摘要： Tire comprising at least two sidewalls, a crown provided radially externally with a tread, a carcass-type reinforcing structure and a crown reinforcement, the inner surface of the sidewalls and of the crown forming an inner wall of the tire, at least one portion of said wall being covered with a self-sealing layer comprising a thermoplastic stirene (TPS) elastomer and the tire being able to be inflated to a given service inflation pressure Pi. For any temperature within a given temperature range, between +30° C. and +100° C., the self-sealing layer has a loss factor tan δ of less than 0.2 and a dynamic modulus G* of less than Pi, tan δ and G* being measured at a frequency of 10 Hz.

    摘要： An inflatable article provided with an elastomer layer comprising at least, as major elastomer, a thermoplastic polystirene/polyisobutylene block copolymer, such as a stirene/isobutylene/stirene (SIBS) copolymer, and at least 100 phr of an extender oil. Preferably, this copolymer comprises between 5% and 50% stirene by weight, its number-average molecular weight is between 30,000 and 500,000 g/mol and its Tg is below −20° C. The extender oil is preferably a polybutene oil such as polyisobutylene (PIB) oil. This elastomer layer is able to fulfil not only the role of a self-sealing (puncture-resistant) layer, but also that of an impermeable layer, furthermore with a reduced hysteresis compared to a conventional layer based on butyl rubber. The inflatable article can be, in particular, an inner tube or a pneumatic tire for a motor vehicle.
