Advantages of DuPont Teflon Coatings

Filed under: Articles

Teflon is the DuPont Company’s name-brand version of PTFE, or polytetrafluoroethylene. PTFE is a fluorocarbon solid, a high molecular weight compound comprised of carbon and fluorine. It is well-known for its hydrophobic properties—neither water nor substances containing water can wet PTFE, thanks to the material’s London dispersion forces caused by the high electronegativity of its fluorine content. PTFEs—and Teflon in particular—are also well-known for having an exceptionally low coefficient of friction.

DuPont Teflon coatings are popular for industrial applications, as it offers a range of beneficial characteristics when applied to parts, components, and equipment used in industrial settings. As Teflon coatings are available in both powder and liquid form, they have proven very versatile and can be used on almost any surface. Among Teflon’s useful characteristics:

  • Nonstick/Nonwetting: Almost no solid substances will permanently adhere to Teflon. Teflon is oleophobic and hydrophobic, preventing oils and water from affecting its surface.
  • Low Coefficient of Friction: In the range of 0.05 to 0.20, Teflon’s coefficient of friction is among the lowest for any substance on Earth.
  • Extreme Temperature Stability: A DuPont Teflon coating will remain stable at temperatures as high as 550°F (285°C) and as low as -454°F (-270°C).
  • Chemical Resistance: The strength of its carbon-fluorine bonds makes Teflon highly non-reactive in chemical environments. The material is completely chemically inert.
  • Dielectric Properties: DuPont Teflon coatings exhibit outstanding dielectric stability over a range of frequencies, as well as low dissipation factors and very high surface resistivity.
