> Teflon for example, is pretty stable when manufactured and in-application. Chemical stability isn't necessarily a good thing. Another chemical, Perfluorooctanoic (C8), is used in the manufacture of Teflon and is extremely stable, so much so that it's found in the bloodstream of 98% of Americans. Unfortunately C8 bio-accumulates and is in fact very harmful. Also, one of the applications of Teflon is cookware and when heated Teflon undergoes thermolysis and forms toxic compounds. So stability is great until it's not. Speaking of how shitty DuPont is... 3M was DuPont's sole supplier of C8 and stopped manufacturing it amid rising concerns from the EPA, so DuPont started manufacturing it on their own.
