PTFE (nonstick coating marketed under Teflon) is safe unless you inhale a lot of its fumes by heating it to over 500F. And by a lot I mean cases of fume fever show up with people welding lots of ptfe. You are probably thinking of Perfluorooctanoic acid, which is carcinogenic but most exposure happens from fabric coatings. It was banned in the US in 2013 and none of it is manufactured or used in the US currently. Which is an example of regulation of additives to plastics. The plastic itself (PTFE) isn’t the problem, it’s the additives. I’d point out interestingly PTFE is what Goretex is made out of. You heat PTFE then jerk it hard and it foams into a fabric. |

Yes and what additives are being added to the PTFE in your non stick pan now? Do you know? Are they proven safe or merely not banned yet?
