Process for making a fluid-impermeable layer, and an impermeable hose

摘要

A process for making a fluid-impermeable layer in a hose having one or more resin layers, and/or one or more rubber layers, and/or one or more thermoplastic elastomer layers, in which a metal plating layer as a fluid-impermeable layer is formed by wet plating on at least one of its resin, rubber and thermoplastic elastomer layers. An impermeable hose having a fluid-impermeable layer made by that process. The hose shows a high level of fluid impermeability, and is also excellent in flexibility, since the metal plating layer can be formed with a very small and uniform thickness without having any pinhole.
