Patent ID: 8646500

Claim:
A puncture-resistant multilayer laminate that is impermeable to inflation gases, usable in an inflatable article, comprising: a gastight first elastomer layer comprising a thermoplastic elastomer copolymer with polystyrene and polyisobutylene blocks (hereinafter “first elastomer”), and optionally an extender oil with a content within a range of 0 to less than 100 phr wherein said first elastomer represents more than 70% by weight of all elastomers present in said gastight first elastomer layer; and a self-sealing second elastomer layer comprising a thermoplastic styrene elastomer (hereinbelow “second elastomer”), identical to or different from the first elastomer, and an extender oil with a content greater than 200 phr wherein said second elastomer represents more than 70% by weight of all elastomers present in said self-sealing second elastomer layer.
