The article says PFAS, but I'm going to guess it is Flourinert[1].
The whole thing about fluorinated hydrocarbons is that it can't burn through oxidation.
Probably a very hard thing to swap out without compromises on fire hazard or corrosion.

- legulere 5y agoWikipedia lists FC-70, FC-72 and FC-75 as compounds of Flourinert. With my limited school understanding of chemistry those all look like they have perfluoroalkyl-parts and therefore fall under the PFAS definition.
