    • La présente invention concerne un tube multicouche comprenant successivement dans sa direction radiale de l'extérieur vers l'intérieur : une couche extérieure en polyamide 11 ou 12, une couche de liant, une couche éventuelle d'EVOH, une couche éventuelle en PA 6 ou en mélange de PA 6 et de polyoléfine à matrice PA 6 et phase dispersée polyoléfine, une couche intérieure à base de PA 6 en contact avec le fluide transporté. Selon l'invention, la couche intérieure comprend en poids, le total étant 100% : 40 à 65% de PA 6, 0 à 20% de PEHD, 10 à 30% d'au moins un polymère P1 choisi parmi les modifiants choc et les polyéthylènes, l'un au moins du PEHD et de P1 étant fonctionnalisé en tout ou partie, 5 à 30% d'un matériau électroconducteur. Le tube de la présente invention est très peu perméable à l'essence particulièrement aux hydrocarbures et à leurs additifs, en particulier les alcools comme le méthanol et l'éthanol ou encore les éthers comme le MTBE ou l'ETBE. Ces tubes ont aussi une bonne tenue aux carburants et aux huiles de lubrification du moteur. Ce tube présente de très bonnes propriétés mécaniques à basse ou à haute température. L'invention concerne aussi l'utilisation de ces tubes pour le transport d'essence.

    • The present invention relates to a multilayer tube comprising, in its radial direction from the outside inwards: an outer layer (1) made of a polyamide, a tie layer(2) comprising, by weight: 1 to 50% of an impact modifier chosen from elastomers and very low density polyethylene, the said impact modifier being completely or partly functionalized, per 99 to 50% of at least one copolyamide 6/12 respectively, an optional EVOH layer (3), optionally a tie layer, an inner layer (4) made of PA 12, PA 6 or a PA 6 - polyolefin compound with a PA 6 matrix and a dispersed polyolefin phase, the layers being successive and adhering to one another in their respective contact zones. The inner layer is the layer in contact with the fluid being transferred. According to one embodiment of the invention, the inner layer (4) contains an electrically conducting material, producing a surface resistivity of less than 10 6 Ω. According to another embodiment of the invention, the inner layer (4) contains essentially no electrically conducting material and the tube includes a layer (4a) that adheres to the layer (4), this layer is made of polyamide and contains an electrically conducting material producing a surface resistivity of less than 10 6 Ω This layer (4a) becomes the inner layer. These tubes may have an outside diameter of 6 to 110 mm and a thickness of around 0.5 to 5 mm.
