Patent ID: 8563098

Claim:
An inflatable article comprising a gastight layer impermeable to inflation gases, wherein the gastight layer is formed of at least an elastomer composition that includes: a thermoplastic styrene (TPS) elastomer, the thermoplastic styrene (TPS) elastomer being a predominant elastomer by weight; and a platy filler, wherein the platy filler has an equivalent diameter (D V (0.5)) of between 20 and 45 micrometers, and wherein in that the platy filler has a shape factor (F) greater than 65 with: F = S BET S sphere = ρ ⁢ ⁢ S BET ⁢ D V ⁡ ( 0.5 ) 6 , in which: S BET is a specific surface area of the platy filler, in m 2 /g, measured by a BET method, S sphere is a specific surface area of a sphere having a same density and an identical equivalent diameter (D V (0.5)), in m 2 /g, as the platy filler, D V (0.5) is an equivalent diameter, in μm, and ρ is a density of the platy filler, in g/cm 3 .
