Zusammenfassung: | 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. |
