<p><P>PROBLEM TO BE SOLVED: To provide a hose for fluid which has excellent texture with gloss on the outer surface, and is almost free from stain deposits and from which the stain deposit is easily wiped off. <P>SOLUTION: In this hose for fluid, an olefin-based thermoplastic elastomer (TPO) composed of a polypropylene (PP) and an ethylene-propylene-diene rubber (EPDM), is used for an inner layer as an inside layer. Further, a reinforcing layer is formed by braiding or wrapping on the outer peripheral surface of the inner layer, and an outer layer of the olefin-based thermoplastic elastomer (TPO) is formed on the outer peripheral surface of the reinforcing layer. In addition, a protecting layer of a modified polyolefin into which a polar group is introduced, is formed on the outer peripheral surface of the outer layer by graft reaction. The protecting layer preferably has 40 to 60 Shore D hardness and 0.05 mm or more thickness. Besides, it is possible to use the hose for fluid as a twin-hose pipe or a multi-hose pipe which is structured of not less than two pieces of the hose joined together in parallel. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
