Properties of DuPont Teflon® Industrial Coatings
The following characteristics are common to all Teflon® coatings in varying degrees. The properties inherent to all Teflon® coatings make them an excellent choice for many applications.
Non-Stick - Very few solid substances will permanently adhere to a Teflon® coating. While tacky materials may show some adhesion, almost all substances release easily.
Low Coefficient of Friction - The coefficient of friction is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and type of Teflon® coating used.
Heat Resistance - Teflon® can operate continuously at temperatures up to 550ºF, and can be used for intermittent service up to 600ºF with adequate ventilation.
Chemical Resistance - Chemical environments usually do not affect a Teflon® coating. The only chemicals known to affect these coatings are molten alkali metals and highly reactive fluorinating agents.
Non-Wetting - Since Teflon® finishes are both hydrophobic and oleophobic, cleanup is easier and more thorough.
Unique Electrical Properties - Over a wide range of frequencies, Teflon® coatings have a high dielectric strength, low dissipation factor, and high surface resistivity.
Cryogenic Stability - Many Teflon® coatings can withstand temperatures as low as -454ºF without loss of physical properties.
