alt Hacker News> the Teflon chemical
Teflon is PTFE, which is fully fluorinated but is also very much a plastic: it’s a highly unreactive solid at reasonable temperatures (which sadly do not include temperatures commonly encountered on stoves).
By “the Teflon chemical” are you perhaps referring to the various nasty liquid, water-soluble surfactants commonly used in factories that make or process PTFE? Those include PFOA, PFOS, and the newer and not obviously any safer “GenX” compounds.
Yes, they are referring to PFOA/PFOS; they're talking about PFAS which is the broad class of chemical compounds that includes PFOA/PFAS. And PFAS are not plastics.
