PROBLEM TO BE SOLVED: To achieve excellent mold releasability, fuel oil resistance, flexibility, softness and slipping easiness and enable applications to fuel conveyance, medical catheters and the like by forming a composite tube by laminating a silicone rubber on a fluoro-material tube. SOLUTION: A composite tube is formed by laminating a silicone rubber on the external surface of a fluoro-material tube made of tetrafluoroethylene/ perfluoropropylene copolymer, considering advantages in thinness, flexibility, workability and operability. This formation improves mold releasability and fuel oil resistance while retaining the chemical resistance, flexibility, softness and slipping easiness of silicone rubber tubes, thus enabling applications to fuel conveyance, catheters and the like. |
