Zusammenfassung:A multilayer tubular structure for transporting fluids for a motor vehicle, the structure including at least three layers: at least one layer having a composition predominantly including at least one semi-crystalline aliphatic polyamide, the composition having at least 50% of recycled material from a single-layer and/or multilayer tube that has been intended for transporting fluids for a motor vehicle, the tube having a composition which predominantly includes at least one polyamide, at least one layer having a composition predominantly including at least semi-crystalline aliphatic polyamide and optionally at least one impact modifier, and when the layer has a composition predominantly including at least one semi-crystalline aliphatic polyamide that is PA12 and/or PA612 and/or PA1010, then the composition includes the impact modifier, and at least one barrier layer, the layer and the barrier layer each having at least 90% of non-recycled material.
