Abstract: A hose comprising a laminate including a rubber layer comprising a rubber composition containing as essential components (A) a rubber made of at least one material selected from the group consisting of an ethylene-propylene-diene terpolymer and an ethylene-propylene copolymer, (B) a vulcanizing agent containing a peroxide, (C) a resorcinol compound, and (D) a melamine resin; and a layer made of at least one material selected from the group consisting of a polyamide resin, an ethylene-vinyl alcohol copolymer, and a metal. In such hose, the rubber layer and the non-rubber layer made of the polyamide resin, the ethylene-vinyl alcohol copolymer, or of the metal adhere well to each other, without applying an adhesive to an interface therebetween.

Abstract: A hose of impermeability has a wall corrugated along at least a part of its length, and formed by an inner thin resin layer, a laminated layer including a metal film, or a layer formed by a metal film, and an outer thin resin layer. It has a very high fluid impermeability owing to its wall layer including or formed by a metal film, and is also very flexible, capable of absorbing vibration, light in weight and strong. A tubular inner thin resin layer is formed by extrusion as the innermost layer of a multi-layered hose wall, and a laminated tape including a metal film, or simply a metal film is spirally wound or longitudinally lapped about the inner resin layer. An outer thin resin layer is formed about a layer formed by the laminated tape, or metal film, and the whole is at least partly corrugated. Alternatively, corrugation is done before an outer thin resin layer is formed by electrostatic powder coating.
