The fan shroud is a critical component in the cooling system. The stiffness, dimensional stability and temperature resistance are critical in maintaining the positioning of the fan to the radiator. The natural damping characteristics of Vydyne PA66 help eliminate vibration that leads to NVH issues. Also, the chemical resistance of PA66 eliminates problems with typical automotive chemicals.
Ascend's Vydyne R860 is ideal for this application because of its superior stiffness and temperature resistance. Alternately, Vydyne R860 brings to the application an optimal balance of stiffness, damping characteristics and chemical resistance. And Vydyne PA66 resins can be more cost effective than competing resin systems. The Ascend automotive team used mold flow analysis and years of fan shroud experience to create optimal parts for Ford,® General Motors® and Chrysler.®
