How are Teflon® Nonstick Coatings Made?
Cookware with Teflon® brand nonstick coatings are manufactured using a liquid coating supplied by DuPont. 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. The pan is baked in a high-temperature oven to remove the liquid and to ensure that the coating adheres to the metal pan. The finished coating is a dried, durable nonstick material which delivers the easy clean and nonstick performance that you expect from your cookware coated with Teflon® nonstick.
DuPont nonstick coatings for cookware are based on PTFE (polytetrafluoroethylene), which is a high-performance fluoropolymer. PTFE has received attention in recent years due to questions about PFOA, which is a processing aid that has been used to manufacture PTFE. DuPont is moving to next generation technologies so that PTFE can be made without the use of PFOA. In 2009 we began to convert customers to the use of these new coatings.
