I am writing to make you know that we are producing about 1 million vehicles per year and we produce our fuel lines which are more than 65 part numbers by co-extrusion of multylayer PA12-Tie-PA6 structure. We ahve already decided to change our fuel lines structure into a monolayer structure wich has less weight and cost... Withal we have started a project to use PA6-nanoclay instead of 3 layer structure.I would appreciate it if you let me know if you have any product to replace our 3 and 5 layer fuel pipes.
