Abstract

<P>PROBLEM TO BE SOLVED: To obtain a hose having excellent permeation-resistance and flexibility by constructing a hose having double structures wherein a highly permeation-resistive tube is used in an inner tube and an outer tube having flexibility is coated on an outer peripheral part of the inner tube. <P>SOLUTION: In the permeation-resistive flexible hose 1, an outer tube 3 made of a tetrafluoroethylene-perfluoroalkylvinyl ether copolymer resin (PFA) is coated on an outer peripheral part of an inner tube 2 made of a tetrafluoroethylene resin (PTFE) having high specific gravity. <P>COPYRIGHT: (C)2009,JPO&amp;INPIT
