1. An inflatable article comprising an elastomer layer that is airtight to at least one inflation gas used to inflate the article,
wherein the elastomer layer includes:
a styrene thermoplastic elastomer;a polyphenylene ether; anda polyisobutylene extending oil at a content of between 67 and 100 phr, wherein the styrene thermoplastic elastomer is a styrene/isobutylene/styrene triblock copolymer (SIBS), wherein the polyphenylene ether is poly(2,6-dimethyl-1,4-phenylene ether); and wherein a content by weight of polyphenylene ether represents between 0.5 and 2 times a content by weight of styrene present in the styrene thermoplastic elastomer.
