tetrafluoroetileno

Tetrafluoroetileno, often abbreviated as TFE, is an organofluorine compound with the chemical formula C2F4. It is a colorless gas at room temperature and pressure, and it is highly flammable. TFE is the monomer from which polytetrafluoroethylene (PTFE), more commonly known as Teflon, is polymerized.

The synthesis of TFE typically involves the pyrolysis of chlorodifluoromethane (CHClF2) or other fluorinated hydrocarbons. The resulting TFE gas is then purified and can be polymerized under specific conditions, often using free-radical initiators. The polymerization process involves the joining of many TFE monomers to form long chains of PTFE.

PTFE, the polymer derived from TFE, possesses exceptional properties including high chemical resistance, low friction, and excellent thermal stability. These characteristics make it suitable for a wide range of applications, such as non-stick cookware coatings, electrical insulation, seals, gaskets, and in the medical field for implants and tubing.

While TFE itself is a reactive monomer, its polymerization into PTFE renders the polymer inert and safe for most applications. Handling of TFE requires precautions due to its flammability and potential toxicity if inhaled in high concentrations. It is generally produced and handled in industrial settings under controlled conditions.
