A 'non-stick surface' is engineered to reduce the ability of other materials to stick to it. Non-sticking cookware is a common application, where the non-stick coating allows food to brown without sticking to the pan. Non-stick is often used to refer to surfaces coated with polytetrafluoroethylene (PTFE), a well-known brand of which is Teflon.
Food sticks easily to a bare metal cooking surface; it must either be oiled or seasoned before use. [8] The coating known as seasoning is formed by a process of repeatedly layering extremely thin coats of oil on the cookware and oxidizing each layer with medium-high heat for a time.
Steel or aluminum cooking pans can be coated with a substance such as polytetrafluoroethylene (PTFE, often referred to with the genericized trademark Teflon) in order to minimize food sticking to the pan surface. There are advantages and disadvantages to such a coating.
The real-life story, which is in theaters now, follows Ohio attorney Rob Bilott (portrayed by Mark Ruffalo) as he steadfastly pursues a case against DuPont, the chemical company that created Teflon.
Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from Teflon pans, according to the National Capital Poison Center.
Cooking anything with fat (meaning oil, shortening, or butter) will help bake layers into the pan, contributing to its natural nonstick coating.
The commonly known brand name of PTFE-based composition is Teflon by Chemours, [4] a spin-off from DuPont, which originally discovered the compound in 1938. [4] Polytetrafluoroethylene is a fluorocarbon solid , as it is a high- molecular-weight polymer consisting wholly of carbon and fluorine .
The fairly inert methyl groups are not very reactive, giving the silicone a fairly low coefficient of friction. Just like Teflon, this makes them non-stick and easy to clean. They are also resistant to very high temperatures due to the strong bonds between all of the atoms. This means that they can be baked or used around hot oils.
