<p>PROBLEM TO BE SOLVED: To provide a polyamide-based multilayer tube for transporting gasoline. SOLUTION: Layers 1-3 are provided toward the outside from the inside. A first layer 1 consists of a mixture of polyamide P1/polyolefin PO1 having polyamide P1 as a matrix or the first layer 1 consists of polyamide P1. The layer 2 consists of copolyamide and the layer 3 consists of polyamide P3. (P1 and P3 are same or may be different and respective layers 1, 2 and 3 are continued and mutually bonded in the respective contact regions.) Furthermore, an EVOH layer or a layer containing conductive carbon black may be added to these three layers (1, 2, 3).</p> |
