FUEL-BARRIER MATERIAL AND MOLDED ARTICLE FORMED THEREFROM

摘要

A fuel-barrier material which has all of excellent heat resistance, chemical resistance, and oil resistance, is melt-moldable, and is excellent in flexibility and impermeability to fuels. Also provided are a molded article formed from the fuel-barrier material and a fuel tube and fuel hose comprising a layer formed from the fuel-barrier material. The fuel-barrier material comprises 95-20 wt.% fluororesin (A) and 5-80 wt.% crosslinked fluororubber (B), wherein the fluororesin (A) is a copolymer of tetrafluoroethylene and hexafluoropropylene or a copolymer of tetrafluoroethylene, hexafluoropropylene, and a perfluoro(alkyl vinyl ether) and the crosslinked fluororubber (B) has a fluorine concentration of 68 wt.% or higher, at least part of the fluororubber (B) having been crosslinked.
