Abstract:
1. A single layer substrate useful for electronic or electrical applications either alone or as a component of a multilayer structure, the single layer substrate comprising a polymeric blend of at least a polyimide component and a fluoropolymer component, wherein: a. the fluoropolymer component is present in a range between and including any two of the following: 9, 10, 15, 20, 25, 30, 25, 40, 45, 50, 55, 60, 65, 70, 75, 80, 90, 95, 100, 110 and 120 weight parts per 100 weight parts polyimide component, and b. the fluoropolymer component; c. wherein the single layer substrate has an outer surface and an interior core, the outer surface comprising an amount of fluoropolymer component greater than the amount of fluoropolymer component present in the interior core; and the interior core comprising an amount of polyimide component greater than the amount of polyimide component present at the outer surface.
