GreenPan™ does not use PTFE, but brings with Thermolon™ non-stick technology a healthy alternative to the market. Thermolon™ is heat resistant up to high temperatures. This means that GreenPan™ has an extra safety feature; if you overheat your pan, even up to 450°C/850°F, no toxic fumes will be released and the coating will not blister or peel.
