Teflon® coatings are used throughout industry in military, space, commercial and consumer applications. Teflon® has the lowest coefficient of friction of any solid material known. It is used as a non-stick coating for pans and other cookware. PTFE Teflon® is very unreactive, and so is often used in containers and pipe work for reactive chemicals. Its melting point varies between 260 °C (FEP) and 327 °C (PTFE), depending on which specific PTFE Teflon® resin has been applied. Other applications include: electrical insulation, gaskets, and sliding contact surfaces

  • Metals which can be readily PTFE Teflon® coated are: Aluminum, Titanium, Steel, Stainless Steel, Monel, Inconel, and Brass. 

  • Plastics, Rubber, Glass, and other materials may also be coated with PTFE Teflon®.

  • PTFE Teflon coatings also has excellent low coefficient of friction properties. Few substances will adhere to Teflon® coatings. 

  • Some PTFE Teflon® coated surfaces will withstand extreme cold temperatures without loss of performance properties and characteristics.

  • PTFE Teflon® has excellent electrical properties especially at radio frequencies, making it eminently suitable for use as an insulator in cables and connector assemblies. Combined with its high melting temperature this makes it the material of choice as a high performance substitute for the weaker and more meltable polythene that is commonly used in low-cost applications.

  • Amongst many other industrial applications, PTFE Teflon® is used to coat certain types of hardened, armour-piercing bullets, so as to reduce the amount of wear on the firearm's rifling. These are often mistakenly referred to as "cop-killer" bullets on account of Teflon's supposed ability to ease a bullet's passage through bullet-proof armour. Any armour-piercing effect is, however, purely a function of the bullet's velocity and rigidity rather than a property of PTFE Teflon®.

PTFE Teflon® is the brand name of a polymer compound discovered by Roy J. Plunkett (1910-1994) of DuPont in 1938 and introduced as a commercial product in 1946. Teflon is polytetrafluoroethylene (PTFE). Teflon is also used as the trade name for a polymer with similar properties, perfluoroalkoxy polymer resin (PFA):
