Teflon is known to not interact when it is in its stable long polymer state. But if we accept that it is breaking away from that state, we know it is not stable, and is potentially reactive.
Personally, a touch of avocado oil in a coast iron is much (much) lower risk (and price) than taking bets on whether this particular PFAS matrix will see the same fate as all the prior (now banned) ones or if we have somehow finally solved PFAS once and for all.
Not to mention all the known-bad environmental PFAS’s the manufacture and disposal of these 2 year pans creates.
But what is it gonna do? The teflon isn't gonna do anything, maybe the binders/glue, but aslong as there's no new discoveries...
