What is the difference between a teflon and nonstick frying pan?
assistant
A Teflon pan is made of a material called polytetrafluoroethylene, which is a synthetic polymer. This material has a very low surface energy, so food slides right off it. Nonstick pans are made of materials such as PTFE or PFOA, which have a higher surface energy than Teflon, making them more difficult to clean.
