PTFE or Poly Tetra Fluoro-ethylene is a Polymer commonly used as insulation but also used to coat non-stick frying pans.
Perhaps the coating has worn off; may be better to use stainless steel pans
Teflon which is florocarbon polymer
Not an element but the organic polymer polytetrafluoroethylene.
Non-stick refers to a type of coating that prevents food from sticking to cookware, while Teflon is a specific brand name for a non-stick coating made by Chemours. In essence, Teflon is a type of non-stick coating, but not all non-stick coatings are Teflon.

There really is no way to prevent the flaking that eventually comes from using non stick pans. The coating with heavy usage really only lasts a couple of years before you will have to buy new ones if you do not like the flaking.
The best brands of non-stick frying pans are cuisnart and Anolon. They are both highly rated and very popular.
