FUEL HOSE AND ITS MANUFACTURE

摘要

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