Andy;
CTE = 7-9 ppm/degree C
Dk (w/ hi temp epoxy) = 3.9
Dk (w/ polyimide) = 3.6
Tg (w/ hi temp epoxy) = 150-180C
Tg (w/ polyimide) = 210-250C

sources:  Arlon, Dielektra GmbH, Isola Werke, NELTEC, and Polyclad NH

this is all from a DuPont brochure dated 2/20/96
there is a phone # for additional info: 800/453-8527

Hope it helps
Fred J.

By the way; I understand water absorbtion is a big issue with this
material (becasue of the aramid fiber).
