I am looking for information of how the dielectric constant varies over frequency for the plastic PEEK natural (no filling material) (PolyEtherEtherKetone).

I don't know about frequency variation, but I dug up two numbers:

DK=3.5
DF=0.004

There might be some threads to pull on wikipedia:
en.wikipedia.org/wiki/PEEK

Good luck!

Steve
