<p><P>PROBLEM TO BE SOLVED: To provide a multilayer hose which is superior in barrier properties to a fuel containing an alcohol, has an intermediate layer exhibiting the strong adhesion to an inner layer rubber layer, contains adhesive components superior in extraction-proof properties, and, can be suitably used as, for example, a fuel hose for cars. <P>SOLUTION: In the multilayer hose, the intermediate layer 1B is made of a resin containing polyphenylene sulfide as a main component, and rubber layers are arranged as an inner layer 1A and an outer layer 1C, and the three layers are laminated. The inner layer of the hose is made of fluororubber, and the intermediate layer is directly laminated on the fluororubber layer. The above intermediate layer includes an alloy or a blend of polyhenylene sulfide with at least one polymer selected from the group consisting of a polyolefin, a polyamide, a fluororesin, and a polyester resin. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
