Truck Window With DuPont™ Rynite® and Delrin® Wins Award

The window's innovative design keys on the performance and design freedom afforded by DuPont™ Rynite® PET thermoplastic polyester and DuPont™ Delrin® acetal.



"The sleek flush-mount design of our HPS G-1.0 window represents a major styling and functional advance over other sliding truck windows," said Phil Taylor, Guardian's product marketing manager for the new unit.



The sliding truck window is available in the automotive aftermarket for GMC Sierra and Chevrolet Silverado pickups. Versions for Ford F150 and Dodge Ram trucks are due out in March 2007.



The new window has upper and lower guide rails molded from Rynite® PET. Their design is crucial to the window's innovative flush-mount feature with guide channels that have an angled change of direction near each side of the window opening. The angled channel guides the sliding center window assembly into alignment with the fixed window as it closes.



The slider assembly is held in the rail by guide components mounted at the top and bottom of the carrier. Molded from Delrin® 100AL, formulated for especially low friction properties, the guide travel smoothly in channels in the upper and lower rails made of Rynite®. The upper guides are spring-loaded to maintain their position in the upper rail's channel. Delrin® 100AL also provides the good strength, stiffness and dimensional stability required for the guide components.
