Non-stick coating is not toxic. A common non-stick coating is Teflon coating. Cookware using Teflon non-stick coating will not undergo any change in the temperature range from normal temperature to 260°C, but when the temperature exceeds 260°C, the coating gradually becomes unstable. However, it is difficult to reach a temperature above 260 degrees during daily cooking, so no toxic substances will be produced during normal cooking.

Common types of non-stick pans

1. Teflon non-stick pans

Teflon is the transliteration of Teflon. Teflon is a registered trademark of DuPont used on a range of fluoropolymer products. In 1954, Colette, the wife of French engineer Marc Grégoire, suddenly had the idea that Teflon, the non-stick material her husband used to coat fishing lines to prevent knots, would be very effective if it could be used on frying pans. The "non-stick pan" that saved countless modern housewives was born.

2. Ceramic-coated non-stick pans

Ceramics play an important role in the upgrade process of non-stick pans. Ceramics have stable performance and have been fully proven to be safe after thousands of years of use. The use of nanotechnology makes the surface of the product tight and non-porous, achieving a non-stick effect.

Can a scratched non-stick pan still be used?

A scratched non-stick pan can still be used, but its non-stick effect is basically It doesn’t work anymore. Therefore, when using a non-stick pan, brush the pan with a book instead of wire mesh. Use iron wire balls or other things to brush gently. Once the coating on a non-stick pan is damaged, it basically loses its non-stick effect.
