Abstract

A layered molding and method for making the same which has excellent antipermeability to gasoline. The layered molding is defined by a fluoroplastic and an epichlorohydrin rubber. The fluoroplastic is a copolymer formed from at least two precursors selected from the group consisting of hexafluoropropylene, tetrafluoroethylene, and vinylidene fluoride, which are selected within a plotted range to preferably form a binary or tertiary composition. The epichlorohydrin rubber contains organic phosphonium. The resulting layered molding does not require an adhesive agent.
