Case file: Tubing for SCR


Rilsan® is recognized as one of the best polymers for the automotive industry, and is specified by many automotive OEMs for various under-the-hood / powertrain applications such as fuel management and transport systems (in-tank tubing, monolayer or multilayer fuel lines, etc.), water-based cooling, under-pressure or vacuum tubing systems such as hydraulic flexible pipes (clutch, brake hose, power steering, etc.), pneumatic tubings and pneumatic servo brake systems (brake booster, etc.) 


Rilsan® is also used to produce tubing for the SCR (Selective Catalyst Recovery) Clean Diesel Technology, allowing a reduction in NOx emissions to the atmosphere on new vehicles including heavy goods vehicles.
