There are indications that more than three thousand years ago some ancient Greeks might have made and used nonstick pans to bake bread. Mycenaean Greek skillets had a cooking side covered with tiny holes that archeologists believed helped to evenly spread oil over the griddle so that dough wouldn't stick while being cooked.
In the modern history of nonstick coating technology, while working at Chemours in 1938 Roy Plunkett accidently invented polytetrafluoroethylene (PTFE). Better known today by its trademarked name Teflon®, PTFE coated nonstick cookware started to hit the selling floors in the early 1960s.
PTFE coating's single most important property that makes it so great a choice for nonstick cookware is its very low coefficient of friction (CoF). As a result, most substances (in this case food) won't stick to it and can be easily removed from the cooking surface.
Early PTFE coated cookware suffered from poor quality which often resulted in a short product lifespan. In subsequent years a lot of research and development was conducted to improve the quality and adhesion of today's PTFE coating services. The result is that nonstick cookware, while once considered disposable, now accounts for 75 percent of all cookware and bakeware sold.
The quality of PTFE coatings has come so far that nowadays some manufacturers offer a lifelong guarantee on the coating of their products. PTFE's nonstick characteristic also makes it a very good candidate for a variety of uses and industries outside of the kitchen, including coatings for items such as plain bearings, slide plates, gears, and more. And, a PTFE coating's dielectric properties make it a great choice for insulation in wiring for the aerospace and computer industry.
These applications are just a few of the use cases PTFE nonstick coatings offers. Even as technology continues to evolve and enhance the way we live, PTFE coatings will certainly remain a vital component that enhances and improves our daily lives via the tools and equipment we use.
