Teflon and other Fluoropolymer Coatings:

Teflon was discovered nearly 70 years ago and has been used in precision engineering companies safely on cookware for over 40 years. Teflon has been used since the 1940's on automotive, military, personal use, and industrial products. Many Teflon and other fluoropolymer coatings are permitted for use in contact with food in compliance with the Federal Food, Drug, and Cosmetic Act and applicable regulations.

There is one known health hazard associated with Teflon, inhalation of fumes produced during degradation of the coating. Temporary flue-like symptoms (known as polymer fume fever) can occur when the fumes from overheated fluoropolymers are inhaled. Typically the fluoropolymer coating would have to be heated to an excess of 500°F to begin to depreciate. Fumes are not typically given off until the fluoropolymer significantly decomposes (660°F). Fats, butter, and cooking oil tend to scorch and smoke at only 400°F. When used properly Teflon non-stick products are safe.

For the past six years the precision engineering company has been studying to determine what if any human health effects exist. It is a polymerization aid, not an ingredient, used to help make fluoropolymers. It is largely removed during the final steps of polymer production and by the high temperatures used when most fluoropolymers are made into finished products.

Over the past six years there have been rumors, misconceptions, and unsubstantiated claims regarding precision engineering services of PFOA (Perfluorooctanoic Acid), its safety, and its effect on Teflon and other fluoropolymer coatings. In order to reduce concerns related to PFOA, industry has improved manufacturing processes and controls to reduce the use and emissions of PFOA. The EPA (Environmental Protection Agency) and industry have a stated goal of virtually eliminating the release of PFOA into the environment by 2015.
