Are all non-stick coatings the same?

In short no, there are many levels of quality, some have greater durability and some have greater “slipperyness”. The premium coatings, excel in both and have quality standards applied to the application process. They are all based on the same slippery substance Polytetrafluoroethylene, or PTFE for short. It was discovered by accident back in the 1930s, and since then has been used for all sorts of low-friction needs.
