Accidentally discovered in 1938 by Scientist Roy J.Plunkett the term PTFE Stands for Polytetrafluoroethylene. It is a synthetic fluoropolymer of tetrafluoroethylene.PTFE is commonly known as Teflon which is a very well known brand name by Chemours. The original discovery was made by Dupont.
PTFE is very versatile and has a huge range of applications. It is hydrophobic, nonwetting, high density and resistant to high temperatures. It has the lowest of all coefficient of friction and hence very popularly known for its non-stick properties. The properties of PTFE allow you to solve complex engineering problems. If you compare PTFE to any other fluoropolymer it more often has the best performance to price ratio. It is used as a non-stick coating for pans and other cookware. It is nonreactive,partly because of the strength of carbon-fluorine bonds, hence is it used inlining for containers and pipework for reactive and corrosive chemicals. Also, it is used a lubricant which reduces friction, wear, and energy consumption of machinery.
Advantages of using PTFE (Polytetrafluoroethylene)

* Food Grade Compliant.
* High Thermal Stability and Flame Resistance.
* Resistance to weathering.
* Electric insulation.
* Outstanding Corrosion Resistance.
* No embrittlement or aging.
* Smooth Surface finish Can be achieved.
* Excellent dielectric properties.
* Non-Stick, low co-efficient of friction.
