Until recently, polyesters and copolyesters were not able to be seriously considered for use in an outdoor environment owing to rapid coloration upon exposure coupled with rapid loss of impact properties. Recent work at Eastman has resulted in a coextrusion technology with a high level of UV absorber that has now circumvented both of these problems. A caution on the use of accelerated device exposures will be discussed. Outdoor exposures in Florida, Arizona, and other locations will be presented and compared to the accelerated device exposures and each other. Some of the potential uses of this new technology will also be discussed.
