Teflon® PTFE also has a low coefficient of friction so is ideal for many low torque applications. This material is non-contaminating and accepted by the FDA for use in food services.
Teflon is not banned because it is not poisonous.
Overheating a PTFE-coated skillet can be dangerous. Very high temperatures can cause the PTFE to release gases that can give you “polymer-fume fever.” You'll get the chills, a headache, and yes, a fever. This is rare and would only happen if you heat a nonstick pan on high heat for more than 30 minutes.
You can choose two types of medical grade fluoropolymer coating chemistries for medical devices; an aqueous-based PTFE coating and a solvent-based coating. All PTFE is made by undergoing a free radical polymerization process combining carbon and fluorine atoms.
Essentially, the only difference lies in the name. PTFE is the shortened name of the chemical polytetrafluoroethylene, and Teflon is the trade name of the same polymer. If you are looking for a highly flexible, non-stick material that is chemical, electrical and thermal resistant, look no further than PTFE.

Not exactly, but it's definitely under the microscope. While Teflon itself isn't banned, the chemicals used in its production, like PFOA, have faced restrictions due to health concerns. The EU is working on broader regulations to limit PFAS, which includes Teflon's main component, PTFE.
The International Agency for Research on Cancer reviewed the research on PTFE, and determined the current data was inconclusive with regard to PTFE's potential to cause cancer. However, a wide-ranging literature has linked PFOA, which can be a contaminant of PTFE-containing consumer products, to health effects.
The use of PFOA in the manufacturing of Teflon-coated cookware has been completely stopped. But, even when PFOA is used, it poses little or no harm to your health. Teflon on its own is safe and can't harm you when you ingest it.
PTFE's unique chemical structure distinguishes it from typical PFAS compounds. However, it's important to note that PTFE can contain trace amounts of perfluoroalkyl acids (PFAAs) as impurities resulting from manufacturing.
In general, you want to replace nonstick pans after five years.
ceramic is among the safest material for pans
From dishes, to glasses, bakeware and cookware, ceramic bakeware is our pick for the best cookware material for health thanks to its non-reactive nature and resistance to high temperatures and acidic foods. Plus it's so pretty!
He says PTFE-coated non-stick pans are safe to use but shouldn't generally be used to cook food at very high temperatures. When these pans are heated above 260 degrees Celsius, their PTFE coating can begin to deteriorate.
Consider ceramic and enamel-coated pans as PFOA/PTFE-free alternatives if you are concerned about nonstick coatings' possible health effects. While research is still ongoing in this area, choosing alternative materials can give peace of mind.
If you've decided to swear off PTFE-coated nonstick cookware, there are some good alternatives, including a number of ceramic, cast-iron, carbon steel, and stainless steel pans that perform well in our tests.
The FDA has approved FEP and PTFE for food contact applications due to their inert and non-toxic nature. They do not react with food or beverages, ensuring the safety and quality of the end product.
Never use Teflon tape under brass's compression nut flare threads, or any other compression fitting type. If you're using another type of threading sealant, like pipe dope compound, do not also use Teflon tape. Using both can overload the threads and affect the seal.
Today, most non-stick cookware is made without PFOA. While both synthetic chemicals are classified as PFAS and share a number of properties, PTFE is broadly considered safe to use. PFOA, on the other hand, has been declared carcinogenic to humans by the World Health Organisation.
Non-Stick Coatings in Air Fryers
When overheated (above 260°C), PTFE can break down and release fumes that are potentially harmful to humans and pets. Perfluorooctanoic acid (PFOA), previously used in some non-stick coatings, has been largely phased out due to similar health concerns.
Then, we removed GreenPan entirely from our list of non-toxic cookware. There were two primary reasons: Competing brands began providing independent laboratory testing to prove their products are non-toxic. We became aware of lawsuits against GreenPan that cast doubt on the company's marketing claims.
And when PTFE coatings overheat, they can produce fumes that are deadly to small birds and may be harmful to humans as well. You could describe this occurrence as “the canary in the kitchen,” Peaslee says. In addition, PFAS in pots and pans pose risks even if the chemicals don't migrate directly into our bodies.
There is little doubt that PTFE coatings that are made using PFAS substances will eventually be eliminated, but it is imperative that the industry continues to educate and advocate for a cautious, gradual approach.
Note: As of January 2024, substances containing PFAS are no longer being sold into the U.S. market for food contact use as grease-proofers and their associated authorizations have been revoked by the FDA due to abandonment.
