It has no functionality on the chain of the molecule that can react with anything. It just exists and will exist for an eternity but it will be benign for that entire eternity.
In another similar thread, I thought you said that while PTFE was inert, the manufacturing process for it is pretty harmful.
Like if you have a bottle of lube with PTFE, don't sweat it, but when it's time to replace it, get one without.
