Teflon Â® is a brand name for a man-made chemical known as polytetrafluoroethylene (PTFE). It has been in commercial use since the 1940s. It has a wide variety of applications because it is extremely stable (it doesn't react with other chemicals) and can provide an almost frictionless surface.hile PFOA is used in making Teflon, it is not present (or is present in extremely small amounts) in Teflon-coated products. Because the routes by which people may be exposed to PFOA are not known, it is unclear what steps people might take to reduce their exposure.
