There is a lot information available regarding thermal decomposition e.g. burning, but what happens to PTFE in ordinary environmental circumstances? Or if time for degradation is short enough, what happens in households (indoor air) which contains some PTFE impregnated materials? As far as I understood fluorotelomers might be also involved here somehow, but this is maybe due e.g. some dirt repellent product product which contains those fluorotelomers among PTFE.
One answer can be that PTFE is inert and stable and so fort, yes but I assume that some degradation happens still?
