However you want to define your acronym of choice, it is disingenuous to conflate the fully fluorinated stuff (PTFE and PFA) with the partially fluorinated stuff (PFOA etc). They are very different beasts. All current evidence is that (after manufacturing) PTFE and PFA are as harmless as anything else out there. The partially fluorinated stuff is nasty.
