  • Resin tube for automotive piping and method of manufacturing the same
    Publication number: 20070110938
    Abstract: A resin tube for automotive piping is made of a resin composition containing 6,6-nylon, an impact improver, 6/6,6-copolymer nylon and a plasticizer with a proportion in a mass ratio of the 6,6-nylon:the impact improver:the 6/6,6-copolymer nylon:the plasticizer to be in a range of 100:5-40:5-50:3-20. The resin tube for automotive piping is manufactured by preparing the above resin composition and molding the composition into a tube by extraction. The 6,6-nylon and the impact improver are mixed together in advance and/or the 6/6,6-copolymer nylon and the plasticizer are mixed together in advance.

  • Tube for fuel transportation
    Patent number: 6355321
    Abstract: A tube for fuel transportation according to the present invention includes an innermost layer comprising one selected from the group consisting of fluorine type resins and polyamide type resins, a middle layer comprising a polyalkylene naphthalate resin, an outer layer comprising a thermoplastic resin or a thermoplastic elastomer, and an adhesive layer formed between the innermost layer and the middle layer. Polybutylene naphthalate may be used as the polyalkylene naphthalate resin. The tube for fuel transportation according to the present invention has excellent barrier action against fuels and is highly kink-proof.

  • Fuel transfer tube
    Patent number: 5763034
    Abstract: A fuel transfer tube comprises an inner layer of hot-melt fluororesin and an outer layer of partial aromatic polyamide resin or ethylene-vinyl alcohol copolymer. The layer of hot-melt fluororesin reliably prevents alcohol from permeating into the tube, while gasoline is effectively prevented from permeating into the tube by the layer of partial aromatic polyamide resin or ethylene-vinyl alcohol copolymer. The fuel transfer tube, therefore, is suitable for transferring alcohol, gasoline and a mixture thereof.
