Material helps to improve the fuel efficiency of engines
Stanyl HGR1 is a high-performance material based on Stanyl polyamide 46. This new material reduces frictional torque in automobile engine-timing systems and will provide OEMs with a cost-effective tool for reducing fuel consumption, says the company. Part of the frictional torque arises in engine-timing systems when the timing chain moves over an element that keeps it under tension. This chain tensioner is often injection-molded in polyamide 66, but increasingly this critical component is being replaced with Stanyl HGR1 to reduce frictional torque (by 10% in some applications) where it improves fuel efficiency.— DSM Engineering Plastics, Singpore
