What is PTFE (polytetrafluoroethylene)

PTFE Polytetrafluoroethylene is a high-performance multifunctional fluoropolymer composed of carbon atoms and fluorine atoms. Fluoropolymers are a group of plastics with a wide range of properties and benefits. PTFE is one such fluoropolymer whose discovery forever revolutionized the fluoropolymer group and paved the way for a variety of applications.

One of the common applications of PTFE materials includes non-stick coatings for kitchen cookware. Because of its non-reactivity, in part due to the strength of the carbon-fluorine bond, it is often used to make pipes and containers for reactive and corrosive chemicals.

PTFE is manufactured much like any other polymer. It is manufactured by free radical polymerization technology using TFE addition polymerization in a batch process in aqueous media.

The chemical structure of PTFE is the same as polyethylene; the only major difference is that the hydrogen atoms are completely replaced by fluorine. However, PE and PTFE are prepared in very different ways.

The large size of fluorine atoms forms a uniform, continuous sheath around carbon-carbon bonds, providing the molecule with good chemical resistance, electrical inertness, and stability.
