Inflatable article equipped with a layer impermeable to the inflation gases, of improved hysteresis and impermeability. The layer comprises an elastomer composition comprising at least, as the sole elastomer or as the predominant elastomer by weight, a thermoplastic styrene elastomer (“TPS”) and a platy filler having a volume content greater than 5%. According to one preferred embodiment, the TPS elastomer is a copolymer with polystyrene and polyisobutylene blocks such as SIBS (styrene/isobutylene/styrene) and the composition also comprises an extender oil for the elastomer, in particular a PIB (polyisobutylene) oil. The platy filler is especially chosen from graphites and phyllosilicates such as micas, clays or talcs. The inflatable article can be an inner tube or a pneumatic tire for a motor vehicle.
