Is Polytetrafluoroethylene a Pfas?

A Brief Introduction to PFAS
Its chemical name is polytetrafluoroethylene, or PTFE. PTFE is one of about 4,700 compounds, according to Mulvihill, that comprise a class of chemicals called per- and polyfluoroalkyl substances, also known as PFAS.

Is polytetrafluoroethylene safe to use?

Other than the possible risk of flu-like symptoms from breathing in fumes from an overheated Teflon-coated pan, there are no proven risks to humans from using cookware coated with Teflon (or other non-stick surfaces).

Is polytetrafluoroethylene toxic?

Although in its polymeric form, PTFE is considered to be non-toxic and physiologically inert, with the rise in temperature greater than 260 °C, and PTFE resin produces polymer fumes into the working environment. With further increase in temperature to 350 °C, the fumes can cause polymer fume fever in exposed workers.
