You may already know this, but there are materials
with similar characteristics that are better suited to
multilayer constructions, if you can get away with it.

Maybe compare your needs to Rogers 4350?

We tried that on a previous project and it was good
enough for our 2.7GHz, and saved a ton of money too.

(My only experience with teflon is single-layer
circuits bonded to aluminum palettes, so I can't
help you with your real question.)

good luck,
Jack
