IMPERMEABLE COMPOSITE HOSE

摘要

PROBLEM TO BE SOLVED: To protect metal foil from bending, deforming, and drawing forces acting on a hose in an impermeable refrigerant transport hose and a fuel hose having a laminate layer including the metal foil. SOLUTION: Both inside/outside of the laminate layer are clamped by a thin-film resin layer of an extent for holding the flexibility of the hose into a sandwich state, thereby fixing and protecting the laminate layer and improving the impermeability to the refrigerant etc.
