Can you name one essential application where PFAS is really necessary? Something where society would actually be substantially worse without it. I’m not talking about ski wax here.

- DoingIsLearning 4y agoOnly reasonable example is AFFF fire fighting foam. But realistically the amount of liquid fuel fires that you have to fight in this world probably pale in comparison with the production volumes of unnecessary anti-stick cookware and gore-tex fabrics.
- Jolter 4y agoRight, I suspected that one ... There seems to be some products on the market already: https://firestopperus.com/pfas-free-firefighting-foams/ https://firestopperus.com/pfas-free-firefighting-foams/ Hopefully they don't contain something even more toxic than PFAS?
- themerone 4y agoFirefighting foam is much more likely to contaminate groundwater, so relative production volume is not a good metric for environmental impact. Gore-tex isn't going to hurt anyone unless there is dumping or leakage in manufacturing.

- erosenbe0 4y agoYeah, imagine catheters before ptfe
- erosenbe0 4y agoPtfe gaskets, lubricants, and maybe certain dielectric or insulator applications.
