Fluorine containing Non-stick surface coating

The fluorine containing coating Non-stick surface is a Non-stick surface made of polytetrafluoroethylene as the coating material. Many people worry about the safety of the Non-stick surface coating because of the Teflon incident. In fact, there is a cognitive misunderstanding here. Teflon is only a trademark of the Teflon product, and the toxic and pathogenic ingredient is not Teflon but PFOA. As early as 2015, Non-stick surface coating manufacturers around the world have completely stopped using PFOA, which means that the Non-stick surface we use now no longer contains PFOA ingredients.
PTFE has a wide temperature resistance range and can be used for a long time at temperatures ranging from -180 to 260C without damage. It is also particularly resistant to corrosion, and neither strong acids, strong alkalis, nor strong oxidizing agents can damage its half. It has extremely strong chemical stability. Polytetrafluoroethylene also has high lubricity and physiological inertness, with the lowest coefficient of friction and surface tension in solids, and has super strong non stickiness. Polytetrafluoroethylene itself is non-toxic and harmless. Even if ingested, it will not be dissolved by stomach acid and will be completely eliminated from the body with the digestive system. Based on the chemical properties of polytetrafluoroethylene mentioned above, it is widely used in various kitchen utensils to achieve a non stick effect. But it is not allowed to dry burn over 260 ℃, otherwise white smoke will be generated.
The fluorinated Non-stick surface coating is limited by the process, and the color is mostly black gray, with black high-temperature resistant pigment added. The commonly used copper chrome black pigment is a Ferrous oxide mixed inorganic pigment, with pure color, good blackness, excellent heat resistance, light resistance, chemical resistance and excellent hiding power. It is environmentally friendly and non-toxic.
