FUEL HOSE AND ITS MANUFACTURE

摘要

PURPOSE: To provide a fuel hose and its manufacture wherein a polyamide resin inner layer is integrally formed directly on an inner peripheral surface of a rubber outer layer without via an adhesive. CONSTITUTION: Polysulfide is crosslinked so that its combined density becomes at least 4×10<-5> mol/cm<3> . A polyamide resin powder is laminated on an inner peripheral surface of a rubber outer layer containing a carboxyl group- containing acrylonitrile-butadiene rubber to form a polyamide resin inner layer by heating, and besides that layer is bonded to the rubber outer layer.
