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.
There are some disadvantages to PTFE which give the product some limitations. For example, when overheated, it can release mildly toxic fumes. In addition, its abrasion-resistance is not as good as a number of other coatings and so abrasion resistance isn't its primary advantage.
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.
That's right, Teflon is PTFE but by another name. Teflon is the trademarked brand name for PTFE owned by Chemours, and just as we call our vacuums Hoovers and sticky tape Sellotape, so we've come to know PTFE by the name it was given.
This product goes by various names, including "PTFE tape," after the material used to make it. It's also called Teflon tape, a brand name for PTFE. Some people call it thread seal tape, plumber tape, pipe wrap tape, or seal tape because its most common application is to seal pipe threads in plumbing projects.
PTFE is short for polytetrafluoroethylene, and what makes it so useful is that it's hydrophobic (water repellant) and has very low friction. This makes PTFE tape a must-have for plumbers and anyone who does pipework jobs, such as irrigation contractors.

At normal cooking temperatures, PTFE-coated cookware releases various gases and chemicals that present mild to severe toxicity. Only few studies describe the toxicity of PTFE but without solid conclusions. The toxicity and fate of ingested PTFE coatings are also not understood.
For decades, DuPont used perfluorooctanoic acid (PFOA, or C8) during production of PTFE, later discontinuing its use due to legal actions over ecotoxicological and health effects of exposure to PFOA.
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.
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.
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.
When stored in normal warehouse conditions, all PTFE and Rulon materials have an unlimited shelf life. In fact, a common industry joke is that, at 85 years and counting, PTFE has “not been around long enough” to determine how long it will last!
Polytetrafluoroethylene (PTFE) appears to be the most common fluorinated compound in cosmetics. It is used most widely in anti-aging products and cosmetics, likely because it provides a smooth, sleek finish. PTFE is trademarked as Teflon®, for use in non-stick cookware.
Most air fryer baskets are coated with Teflon or a similar nonstick coating. The majority of air fryers in the market today have Teflon or nonstick-coated cooking baskets. They function similarly to nonstick cookware in that they release food easily and can be cleaned often with just soapy, hot water.
Teflon® is a registered trademark of DuPont and a brand name for polytetrafluoroethylene (PTFE) a nonstick finish. While Calphalon cookware features polytetrafluoroethylene-based nonstick finishes, we are not associated with, nor do we use, Teflon® branded products.
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!
What's the difference between Teflon™ and PTFE? There is NO DIFFERENCE. They are both exactly the same thing, the only difference between them is the name.
Nonstick cookware coated with PTFE is 100% safe to use. 2. Delicate food cooked at lower temperatures comes out better using nonstick cookware.
Choosing between Nylon vs Teflon ultimately depends on the specific requirements of your application. If you need a material that offers strength, flexibility, and durability for mechanical components, Nylon is an excellent choice.
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.
