Delta E Color Change - White PP vs White PVC
We performed weathering studies comparing Flexcon® NexGen™ PP films to our flexible white and frosty clear vinyls and revealed no significant performance difference between the two film types. We assessed total color change (Delta E) and physical degradation in the films over prolonged exposure. Flexcon® NexGen™ had comparable performance to control PVCs for each color (Note: a Delta E value below 2 is not observable to the human eye and, therefore, would be considered a successful test result).
