    • The present invention relates to a multilayer tube comprising, in its radial direction from the outside inwards: a polyamide outer layer (1); an inner layer (2) of a composition comprising, the total being 100%, 5 to 30% by weight of a blend (A) comprising: a polyethylene carrying epoxy functional groups, an impact modifier chosen from elastomers and very low-density polyethylenes, the said impact modifier being completely or partly functionalized; 95 to 70% by weight of a blend (B) comprising: a fluoropolymer (B1), a functionalized fluoropolymer (B2), the proportion of (B2) being between 1 and 80% by weight of (A)+(B), the layers being successive and adhering to one another in their respective contact region. The inner layer is the layer in contact with the fluid being transported. The layer (2) may be conductive. It is also possible to place a polyamide layer (3) beside the layer (2), which layer becomes the inner layer. The tube of the present invention has a very low permeability to petrol, particularly to hydrocarbons and to their additives, in particular alcohols such as methanol and ethanol, or even ethers such as MTBE or ITBE. These tubes also exhibit good resistance to fuels and to lubricating oils for engines. This tube exhibits very good mechanical properties at low temperature and at high temperature. The invention also relates to the use of these tubes for transporting petrol.
    • 本发明涉及一种多层管,其从径向向外包括:聚酰胺外层(1); 组合物的内层(2),其包含总共为100%,5至30重量%的共混物(A),其包含:携带环氧官能团的聚乙烯,选自弹性体和非常低密度聚乙烯的抗冲改性剂 所述抗冲改性剂完全或部分官能化; 95重量%至70重量%的共混物(B),其包含:含氟聚合物(B1),官能化含氟聚合物(B2),(B2)的比例为(A)+(B)的1-80重量% 这些层是连续的并且在各自的接触区域中彼此附着。 内层是与被输送流体接触的层。 层(2)可以是导电的。 也可以在层(2)旁边放置聚酰胺层(3),该层成为内层。 本发明的管具有非常低的汽油渗透性,特别是烃和它们的添加剂,特别是醇如甲醇和乙醇,甚至醚如MTBE或ITBE。 这些管也表现出良好的燃料抵抗性和发动机润滑油。 该管在低温和高温下表现出非常好的机械性能。 本发明还涉及这些管用于运输汽油的用途。
