Teflon is a trademarked name for polytetrafluoroethylene (PTFE), a synthetic resin that is fundamentally defined by its chemical composition of fluorine and carbon.

The connection lies in the molecular structure of the polymer: PTFE is produced by the polymerization of tetrafluoroethylene monomers. In this structure, two fluorine atoms are bonded to each carbon atom in the chain. These fluorine atoms surround the carbon backbone like a protective sheath, creating exceptionally strong carbon-fluorine bonds.12

This specific arrangement is responsible for the unique properties that make Teflon famous, including:
* Chemical Inertness: The dense sheath of fluorine atoms makes the material resistant to attack by almost all chemicals.12
* Low Friction: It possesses one of the lowest coefficients of friction of any known solid, which provides its signature nonstick quality.12
* Thermal Stability: The strength of the carbon-fluorine bonds contributes to its high melting point and ability to function as electrical insulation under high-temperature conditions.12
