Teflon is a brand name of chemical compound of fluorine and carbon called polytetrafluoroethylene (PTFE). The name teflon has now become so popular that it has acquired the position of generic name for this chemical.

Teflon is a plastic material that is highly resistant against chemicals, corrosion, and oxidation.  It can withstand temperatures up to 250 °C. Also it has one of the lowest coefficient of friction against any solid.  It is used in the manufacture of chemical processing equipment and for coating cooking utensils.

Teflon which is widely used as a nonstick coating in cookware, chemical processing equipment and many other applications is chemically known as polytetrafluoroethylene, or PTFE. This was created by scientists at the DuPont Corporation in 1938. The unique molecular structure of Teflon has a chain of carbon atoms as the base like all other polymers we know. But in addition, in Teflon the carbon chain is completely surrounded on all sides by fluorine atoms. As carbon and fluorine form very strong bonds, the fluorine atoms in a way protect the carbon chain which is quite vulnerable. The resulting structure gives Teflon all its unique properties. It is an extremely slippery material and inert to almost all known chemicals
