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 550°F, and can be used for intermittent service up to 600°F 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.
