Abstract
A layered molding and method for making the same which has excellent anti-permeability to gasoline. The layered molding is defined by a fluoroplastic or polyamide plastic 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 epiclorohydrin rubber contains organic phosphonium. The resulting molding layer does not require an adhesive agent.
