The first non-stick pan using Teflon® was marketed in France as "Tefal" in 1954. The surface is so slippery, virtually nothing sticks to it or is absorbed by it; the Guinness Book of World Records once listed it as the slipperiest substance on earth.

The U.S. followed with its own Teflon®-coated pan in 1861. In the cookware plant, this liquid coating is applied directly to the metal surface of the pan; sometimes two or three layers of coatings are applied. Cookware with Teflon™ nonstick coatings are manufactured using a liquid coating supplied by Chemours. They cut one open and found that the TFE had polymerized into a white, waxy powder; polytetrafluoroethylene or PTFE resin.

Plunkett and his assistant, Jack Rebok, were charged with developing an alternative refrigerant and came up with tetrafluoroethylene or TFE. The scientists there were instructed to experiment with the substance, and Teflon® was born.

The first non-stick pan using Teflon® was marketed in France as "Tefal" in 1954. Many common synthetic fibers are polymers, such as polyester and nylon. The TFE was sent to DuPont’s Central Research Department. Ultimately, the challenge was taken out of his hands when he was promoted and sent to a different division. Teflon™ nonstick coatings for cookware and bakeware are made without PFOA/PFOS. A colorless, odorless powder, it is a fluoroplastic with many properties that give it an increasingly wide range of uses. Dr. Plunkett stayed with DuPont until his retirement in 1975. The chemical, also known as PFOS or PFOA, is what gave Teflon its non-stick properties. Another popular brand name of PTFE is Syncolon by Synco Chemical Corporation. Teflon™ is a trademark of The Chemours Company FC, LLC. Like Teflon, a fast food wrapper is made from a PFAS configuration.

The molecular weight of Teflon® can exceed 30 million, making it one of the largest molecules known to man. One of the key ingredients in DuPont’s Teflon was C8, a toxic, man-made chemical created by Minnesota Mining and Manufacturing Company, better known as 3M, to make Scotchgard. More information on Teflon™ nonstick coatings.

Teflon® can be found just about everywhere these days: as a stain repellant in fabrics, carpets, and furniture, in automobile windshield wipers, hair products, lightbulbs, eyeglasses, electrical wires, and infrared decoy flares. Teflon™ nonstick coatings for cookware are based on PTFE (polytetrafluoroethylene)—a high-performance fluoropolymer. When they later checked on the refrigerant, they found the cylinders effectively empty, even though they felt heavy enough that they should still have been full.

Dr. Roy Plunkett discovered PTFE or polytetrafluoroethylene, the basis of Teflon®, in April 1938. The well-known brand name of PTFE-based formulas is Teflon by Chemours. It’s one of those discoveries that happened by accident. It’s still the only known substance that a gecko's feet can't stick to. Although some manufacturers use PFOA to make PTFE, Chemours has never used PFOA in the manufacture of Teflon™ nonstick coatings. He died in 1994, but not before being inducted into the Plastics Hall of Fame and the National Inventors’ Hall of Fame.

PTFE is the polymerized form of tetrafluoroethylene.

The finished coating dries to a durable nonstick material that delivers the easy clean and nonstick performance that consumers expect from cookware with Teflon™ nonstick coatings. Mary Bellis covered inventions and inventors for ThoughtCo for 18 years. He was working with gases related to Freon® refrigerants when he stumbled upon PTFE.

Known by such trademarks as Teflon, Fluon, Hostaflon, and Polyflon, PTFE is distinguished by its slippery surface, high melting point, and resistance to … Both 3M and DuPont were well aware of the health hazards associated with C8.

PTFE has many unique properties, which make it valuable in scores of applications…

The Teflon® Trademark PTFE was first marketed under the DuPont Teflon® trademark in 1945. As for those cooking pans, feel free to take a wire whisk or any other utensil to them – unlike in the old days, you won’t risk scratching the Teflon® coating because it's been improved. Access and use of the Teflon™ brand requires a trademark license from Chemours.

He began playing with it, attempting to find out if it would serve any useful purpose at all. Plunkett was an inveterate scientist. Polytetrafluoroethylene (PTFE), a strong, tough, waxy, nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. Chemours was a spin-off from DuPont, which originally discovered the compound in 1938.

He had this new substance on his hands, but what to do with it? Teflon is the registered trade name of the highly useful plastic material polytetrafluoroethylene (PTFE). Teflon is made from PFAS components to to say a fast food wrapper, for instance, is made from Teflon is incorrect. Teflon is generally used on hard surfaces, other variations of PFAS are used on dental floss, waterproof clothing, pizza boxes. Teflon™ nonstick coatings for cookware are based on PTFE (polytetrafluoroethylene)—a high-performance fluoropolymer. No wonder Teflon® was chosen to be used on non-stick cooking pans, but it was originally used only for industrial and military purposes because it was so expensive to make. The pan bakes in a high-temperature oven to remove the liquid and to ensure that the coating adheres to the metal pan. We’re reimagining how we live, thanks to Teflon™ fluoropolymers. Although some manufacturers use PFOA to make PTFE, Chemours has never used PFOA in the manufacture of Teflon™ nonstick coatings. They ended up making about 100 pounds of TFE and were faced with the dilemma of storing it all. Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. ©2020 The Chemours Company. Find favorite recipes that use cookware with Teflon™ nonstick coatings. It was slippery, chemically stable and had a high melting point. Teflon™ nonstick coatings for cookware and bakeware are made without PFOA/PFOS. Polytetrafluoroethylene, also known as Teflon®, is made with four ingredients -- fluorspar, hydrofluoric acid, chloroform, and water, which are combined in a chemical reaction chamber heated to between 1094-1652°F (590-900°C). They placed the TFE in small cylinders and froze them. Creating PTFE involves 2 main phases and a series of reactions.

PTFE is one of a class of plastics known as fluoropolymers. ThoughtCo uses cookies to provide you with a great user experience. A polymer is a compound formed by a chemical reaction which combines particles into groups of repeating large molecules. No wonder Teflon® was chosen to be used on non-stick cooking pans, but it was originally used only for industrial and military purposes because it was so expensive to make. She is known for her independent films and documentaries, including one about Alexander Graham Bell.

Plunkett held a Bachelor of Arts degree, a Master of Science degree, and his Ph.D. in organic chemistry when he went to work at the DuPont research laboratories in Edison, New Jersey.
