Steve,
You may wish to look at a material called Cirlex. http://www.cirlex.com/
I have used it to make BGA sockets and other components. It can withstand very high temps, is slightly plastic, but can be milled, cut, laser etched, bonded, laminated, etc.
It is a derivative of Kapton, but tougher and stiffer.

also named Delrin or POM. You can get a extremly ion free from Hoechst, at
least when we bought from them 10 years ago.
