									Teflon Non Stick Coatings, PFOA, And Cookware - Facts, Myth & What You
Need To Know
Teflon Non Stick Coatings, other leading no stick coating manufacturers
too, are all 'feeling the heat'. And unfairly so.
Why?
Because of the misconception that Teflon (a registered trademark of
DuPont) is synonymous with "PFOA," a term you've come to hear about in
recent years.
Here, we will explain the difference, try to set the record straight. And
tell you how to safely enjoy your no stick cookware.
First, what is PFOA? Also known as "C-8," perfluoro-octanoic acid is a
surfactant, a critical aid in the polymerization of aqueous-based
fluoropolymers. It is also used in the manufacture of many consumer
products today.
Is PFOA dangerous? Well, in 2005, under a risk-assessment study by DuPont
and Environ International, it was determined that PFOA traces are in the
blood of most everyone on the planet. No illness has ever been associated
with this compound, including workers in chemical plants exposed to much
higher levels.
PFOA is not Teflon, the brand we come to identify as a generic name for
DuPont PTFE (polytetrafluoroethylene). Nor is PFOA fluoropolymer. Nor is
PFOA a PTFE dispersion.
And PFOA is not in your no stick cookwares. Why?
Because PFOA is released in the manufacture of the no stick coating
cookware. Measurement for PFOA, even at the parts per billion level, are
undetectable.
Does this make no stick coatings for cookware safe?
Yes, though you should avoid overheating your cookware. While Teflon has
remarkable heat stability, prolonged exposure to cooking temperatures
above 500 degrees Fahrenheit is not recommended. Not only does it reduce
cookware life, over heating can lead to emitting fumes unsuitable for
inhaling. Will they harm you? Worst case - and you would have to breathe
enough of them - would be temporary flu-like conditions, such as chills,
fever or headache. In my many years working with these products,
independently, I have never experienced these symptoms referred to as
'polymer-fume fever'.
What temperatures can your no stick cookware reach? Consider these 'safe'
examples. Scrambled eggs cooked on medium for a few minutes can produce
surface temperatures just over 200 degrees Fahrenheit. For chicken stir
fry, cooked on high for over five minutes, temperatures around 300
degrees Fahrenheit.
Bacon, cooked for about five minutes on high, about 450 degrees
Fahrenheit.
So, what is 'risky cooking'? Consider empty pans pre-heated, with or
without oil, which will exceed 500 degrees Fahrenheit, in just a couple
of minutes. Foods like hamburgers, especially steak, risk even higher
temperatures.
Follow these precautions and cook safely: Avoid metal spatulas. Wood or
plastic cooking utensils are ideal. When storing your cookwares, prevent
scratching by separating cooking surfaces with cloth or paper towel. Do
not heat your cookware empty. Never use high heat. Be sure your kitchen
area is well ventilated. Choose heavier-duty cookware for more heat
absorption. And do replace your cookware the first sign of flaking or
peeling.
With responsible use, your cookware with Teflon Non Stick Coatings should
provide you two or more years of dependable non stick performance.
Now that's smart cooking!
