What is used for coating of non stick frying pan?

The most common coating used for non-stick frying pans is polytetrafluoroethylene (PTFE), better known by its brand name Teflon.

However, there are other materials used for non-stick coatings, including:

* Ceramic coatings: These are often marketed as being healthier and more eco-friendly than PTFE.

* Silicone coatings: These are typically found on bakeware rather than frying pans, but some frying pans use silicone.

* Other fluoropolymers: Similar to PTFE, but with slightly different properties.

It's important to note that:

* PTFE is generally considered safe when used properly and at recommended temperatures.

* Ceramic and silicone coatings are often less durable than PTFE, but they can offer a similar level of non-stick performance.

Ultimately, the best type of non-stick coating for you will depend on your individual needs and preferences.
