I'm not an expert but aren't polymers PFAs i.e. forever chemicals and about to be restricted if not prohibited?

  No. Polymers are a general class of molecules that consist of a long chain of repeated subunits. Plastics are polymers, for example. (Poly - many) PFAs specifically have chains of carbon-flourine bonds, among other differentiators. For geopolymers, a layperson intuition is to think of ceramics (specifically, the binders that hold them together)

      It's not clear from just pasting a link what you're trying to say in this context. Could you elaborate? PFAs and fluropolymers are all fluorine based. Most plastics and geopolymers are not.
