The idler pulley is a critical component in the accessory belt drive system. The stiffness, dimensional stability and temperature resistance are critical in maintaining optimum performance of the system. A smooth surface is needed to minimize the wear on the drive belt. Also, the chemical resistance of the PA66 eliminates problems with typical automotive chemicals.
Ascend’s Vydyne R530H is ideal for this application because of its superior stiffness and temperature resistance. The smooth surface provides for optimum belt life and performance. Vydyne PA66 resins can be more cost effective than competing resin systems. The Ascend automotive team used mold flow analysis and years of cooling fan experience to create optimal parts for Ford,® General Motors® and Chrysler.®
