The surface of the non-stick pan is coated with PTFE, and the PTFE coating of the non-stick pan will not change in the temperature range from normal temperature to 260℃. The temperature used in daily cooking is usually only about 200℃, and even if frying is used, the oil temperature will generally not exceed 250℃. So in normal cooking, there is no need to worry about the decomposition of the coating and the release of harmful substances. However, if dry burning occurs, the temperature will exceed 400℃ in a short time, which will cause damage to the pot and bring health hazards.
Generally speaking, as long as the cooking temperature is properly controlled, there is no need to worry that the Teflon coating of the non-stick pan will decompose harmful substances, so it can be used with confidence and will not endanger human health.
