DSM is collaborating with a growing number of global OEMs and all Tier1s to validate the friction benefit that Stanyl can bring in timing systems. Over half a dozen engines on motored test stands have confirmed a significant friction benefit anywhere between 0.1 and 0.5 Nm friction torque reduction. Changing the wear faces that are in contact with the chain from standard PA66 to Stanyl PA46 is recognised to be the most cost effective way to improve fuel economy in engines. Since Stanyl is known for its superior wear resistance, the friction benefits come at zero risk of any change or re-approval costs, such as would be required for new materials. It simply contributes to building the most robust timing chain systems.
