Pneumatic object provided with a gas tight layer based on a thermoplastic elastomer and a load lamellar

摘要

A pneumatic object or inflatable article includes a gastight elastomer layer. The elastomer layer is formed of a material that includes at least one thermoplastic polyisobutylene block elastomer and a platy filler, such that relationships of: EX′/EZ′1.2 and EY′/EZ′1.2 apply, with Z being a direction normal to the elastomer layer, X and Y being directions orthogonal to Z, and EX′, EY′ and EZ′ being dynamic moduli in compression of the elastomer layer in the X, Y, and Z directions, respectively.
