(57) [Summary] [Structure] A tube having a composition layer containing the following (A) and (B), wherein the composition layer has a thickness of 20 to 80% of the tube wall thickness. Fuel tube. (A) Polyamide 11 resin and / or polyamide 12 resin 100 parts by weight (B) One side length 0.002-1 μm, thickness 6-20 Å Layered silicate having an average distance of 20Å or more between 1.5 to 10 parts by weight. [Effect] It is possible to significantly prevent the fuel from penetrating the wall surface, and to have low-temperature impact resistance, Excellent tube performance such as bending stiffness. |
