Abstract (en)
[origin: WO2011131560A1] An inflatable object provided with an inflating gas-tight layer, having improved hysteresis and improved leak sealing; said layer comprises an elastomer composition comprising at least, as sole elastomer or as majority elastomer by weight, one thermoplastic elastomer ("TPE") and a hydrocarbon-based resin, of which the glass transition temperature of the hydrocarbon-based resin is above 0°C. The TPE elastomer is a copolymer comprising at least one polyisobutylene central block and the composition optionally also comprises an elastomer extender oil. According to another optional embodiment, the composition also comprises a lamellar filler in particular selected from graphites and phyllosilicates, such as micas, clays or talcs. The inflatable object of the invention is in particular an inner tube or an inflatable tyre for a motor vehicle.
