If so, What was your experience with it. Quoting a job and I have never seen the stuff. I know it is a type of plastic.
I have some limited experience with it - more as a user / buyer. In general, acid resistant / F containing polymers are a bit gummy, and tend to have a strict amount of thickness which needs to be removed in the final pass - or the finish is poor.
Stress relief and cold flow can be a big deal.
Sort of like machining a mixture of of very soft copper and pine wood.
