  An inflatable object is equipped with a layer for sealing in an inflation gas. The layer is formed of an elastomeric composition that includes a predominant elastomer by weight, a block thermoplastic elastomer, and a lamellar filler. The block thermoplastic elastomer includes a polyisobutylene block with a number-average molecular mass ranging from 25,000 to 350,000 g/mol and a glass transition temperature of less than or equal to −20° C., and, at at least one end of the polyisobutylene block, a thermoplastic block made from at least a polymerized monomer other than a stirene monomer, the polymerized monomer having a glass transition temperature greater than or equal to 100° C. The lamellar filler has an equivalent diameter (D v (0.5)) of between 15 and 60 micrometers and an aspect ratio (F) of greater than 65.

  Elastomer composition comprising at least, as predominant elastomer, a thermoplastic SIBS elastomer comprising a “polyisobutylene” block and, at least one of the ends of the “polyisobutylene” block, a thermoplastic block of specific structure having a Tg greater than or equal to 100° C. The elastomer composition according to the invention may be used as an elastomer layer impermeable to the inflation gases in an inflatable object. This inflatable object is, in particular, an inner tube or a pneumatic tyre for a motor vehicle.
