Yeah- there are definitely problems with it on pans, but the context of the thread was for PTFE as a water repellent in clothing. As far as I know, the concerns for uses where high heat isn't an issue are related to manufacturing byproducts- which can make their way into the final product, but also if the manufacturer doesn't dispose of them correctly, they can wind up in the environment. It's almost a bit like Agent Orange (though probably not nearly as bad, at least not in the medium-term?)- the intended product isn't the problem, but the manufacturing process makes it really easy to let nasty stuff slip in. But I don't know that much about this, so please correct me if I'm wrong! Not a chemist, I just read a lot.
