You may want to try liquid crystal polymer (LCP). LCP is a flexible material with a Dk of 2.9, a Df of .002 and CTE of 17ppm. I believe that the material is .002 as a standard thickness.
I know that Yamaichi and Rogers make LCP, and I think that Gore does also.

I am aware only of PTFE and Gore speedboard C (contains PTFE) having a dielectric constant that low.

Hello everybody,
I am in need of core material and prepreg material with very low
Di-electric constant(Dk) and low loss factors.Dk is about 3.0 or less with
very thin profile of the material.Di-electric thickness spec will be 2.4mil
or less.Any help on the subject will be appriciated.
Thank you all
