  • Resin tube for automotive piping and method of fabricating the same
    Patent number: 6769453
    Abstract: Nylon 6 having viscosity number within a range of 170-340 in a measurement of a 98% concentrated sulfuric acid solution at 25° C. and a plasticizer are mixed in advance, and then the mixture is mixed with Nylon 66 having viscosity number within a range of 240-370 in the measurement, thus a resin composite is prepared. Then, the resin composite is formed into a tube by extrusion molding. The resin tube thus obtained is used as a resin tube for automotive piping, such as vapor fuel piping to be incorporated into a fuel tank or as oil piping to be incorporated into an engine room.

  • Corrugated resin tube
    Patent number: 6755217
    Abstract: A corrugated resin tube which comprises, in at least one part of an axial direction of the tube, a corrugated portion having an undulated cross section along the axial direction, characterized in that the corrugated portion comprises at least one fiber-reinforced layer made of a thermoplastic resin or a thermoplastic elastomer, which contains inorganic fibers, and at least one resinous layer made of a thermoplastic resin or a thermoplastic elastomer, which contains no inorganic fibers or contains inorganic fibers in an amount less than the amount in the fiber-reinforced layer, wherein these layers are laminated and the outermost layer is the resinous layer. The content of the inorganic fibers in the fiber-reinforced layer is preferably from 5 to 20 wt %, and the thickness of the fiber-reinforced layer is from 30 to 70% of the whole thickness.
