What is Teflon?

Teflon is a synthetic fluoropolymer made up of tetrafluoroethylene monomer. The chemical name of Teflon is poly (1,1,2,2 tetrafluroethylene). It is a thermoplastic polymer. Teflon chemical formula is (C2F4)n. Teflon formula shows repetitive or n numbers of C2F4 units. It has an ability to maintain high strength, toughness and self-lubrication at low temperatures (around 5 K), and good flexibility at temperatures above 194 K.

Properties of Teflon

  • It is a white solid compound at room temperature.

  • Its density is about 2200 kg/m3.

  • Its melting point is 600 K.

  • It is a chemical resistance compound, the only chemicals that can affect these compounds are alkali metals.

  • It shows good resistance towards heat and low temperature.

  • It has a low water absorption capacity.

  • It has an anti-adhesion ability due to which it is used as non-stick kitchen utensils.


Uses of Teflon

  • It is used in making waterproof fabric.

  • It is used in making non-stick cookware.

  • It is used in making an anti-friction device.

  • It is used for coating medical appliances (surgical devices).

  • Due to its high resistance towards corrosion, it is used for coating the lining of the laboratory appliances.


Production of Teflon

Teflon is produced by a free radical mechanism. The net reaction for the production of Teflon is given below:
