Is PTFE tape toxic?

1. PTFE tape is non-toxic under normal conditions. However, when the heating temperature of the coating reaches 260°C, it will begin to volatilize, and when the temperature reaches 350°C, the PTFE tape will begin to decompose. Therefore, the use temperature of non-stick pans with PTFE tape generally cannot exceed 250°C.

2. Polytetrafluoroethylene, also known as Teflon, is a synthetic polymer material that is resistant to alkali, acid and organic solvents. Teflon has a very low coefficient of friction, so it is often used as a coating for the inner layer of non-stick pans and water pipes.

3. When cooking oil and butter, the temperature of cooking utensils is about 200-230℃. When cooking meat, the temperature is about 200-230℃. Therefore, the non-stick pan with PTFE tape is safe and non-stick under normal use. poisonous.
