What material is the non-stick pan coating?

Regarding non-stick pans, the first thing people pay attention to is the coating. However, many people are not clear about what material the coating of non-stick pans are made of, and this has caused some concerns. Next, let us walk into non-stick pans. Pot production process, understand the material secrets behind the coating.
The most common non-stick coating on the market is Teflon. The history of non-stick pan and its coating materials can be traced back to the Second World War. The earliest non-stick pan material was polytetrafluoroethylene (PTFE), also known as Teflon (Teflon), which was discovered by DuPont engineer Roy Plankert in 1938.

At that time, he was trying to make a new chlorofluorocarbon refrigerant, but unexpectedly discovered that tetrafluoroethylene had polymerized in a high-pressure storage container to form a new substance, that is, "polytetrafluoroethylene." This new substance has a high degree of corrosion resistance, most of the strong acids and alkalis (including aqua regia and fluoroantimonic acid), strong oxidants and reducing agents can not help it, and products made of polytetrafluoroethylene Placed outdoors, regardless of the sun and rain, there will be no damage for 20 to 30 years. Therefore, Teflon has another nickname-Plastic King. Because Teflon also has an ultra-low coefficient of friction and surface, it can make it difficult for other substances to adhere to its surface. Since then, Teflon has occupied most of the market for non-stick cookware coatings.

However, what really makes Teflon into the cookware field are its other two properties: ultra-low coefficient of friction and surface energy. Teflon’s coefficient of friction is the smallest among all plastics, and its surface energy is also the lowest among all solid materials. These properties make it difficult for other substances to adhere to its surface. With these two absolute advantages, Teflon occupies most of the market for non-stick coatings.
In recent years, in addition to Teflon, other types of non-stick coatings have also been developed. Japanese Dakin fluorine coatings, American Whitford coatings and ceramic coatings have gradually been accepted by the market. However, Teflon still occupies a major position in the non-stick pan market relying on its excellent performance and high cost performance.
