Accidental discovery
PhD. Roy J. Plankter Gases related to refrigerants are being studied. After examining frozen, compressed samples of tetrafluoroethylene, he and his colleagues made an unexpected discovery: The samples spontaneously polymerized into a white waxy solid, forming polytetrafluoroethylene (PTFE).

How was Teflon discovered?

DuPont chemists discovered by accident on April 6, 1938, PhD. Roy Plunkett At the same time trying to invent a better cooling gas.

Where is PFOA found?

PFOA and some similar compounds can be found at Low levels in certain foods, drinking water, and household dust. While PFOA levels in drinking water are generally low, they may be high in some areas, such as near chemical plants where PFOA is used.

Why is Teflon bad?

Danger of overheating.Generally speaking, Teflon is a Safe and stable compoundHowever, at temperatures above 570°F (300°C), the Teflon coating on nonstick cookware begins to decompose, releasing toxic chemicals into the air (14).
