Polytetrafluoroethylene or PTFE is the commonly used versatile, high-performance fluoropolymer made up for carbon and fluorine atoms. One of the common applications of this polymer is non-stick coating in kitchen cookware (pans, baking trays etc.), hence, you can easily find this in your kitchen.

The chemical structure of PTFE [CF₂-CF₂]_n is like that of polyethylene (PE), except that the hydrogen atoms are completely replaced by fluorine (hence it is referred as perfluoro polymer). However, it is important to note that in practice PTFE and PE are prepared and used in totally different ways.

Apart from used in the kitchen, PTFE is used as a cost-effective solution for industries ranging from oil & gas, chemical processing, industrial to electrical/electronic and construction sector, etc.

Properties of PTFE

Mechanical properties of PTFE are generally inferior to engineering plastics at the room temperature. Compounding with fillers has been the strategy to overcome this shortage. PTFE has useful mechanical properties in its use temperature range.

PTFE has excellent electrical properties such as high insulation resistance, low dielectric constant,has an extremely low dielectric constant (2.0) due to the highly symmetric structure of the macromolecules.
