Machined Fluorosint (500 and 207)

Chemically resistant and dimensionally stable PTFE-based products

Why choose Fluorosint?

  • Chemical resistance in line with PTFE
  • Good wear resistance
  • Continuous operation up to 500°F

What are some common Fluorosint applications?

  • Bearings
  • Bushings
  • Seals
  • Shrouds
  • Hot air or steam applications

Fluorosint 500

The mica fill of this blend allows a very low coefficient of thermal expansion- approximately 40% of unfilled PTFE - along with a lower wear rate than PTFE. Its low coefficient of friction, good electrical properties and chemical resistance and form resistance to 650F make fluorosint 500 an excellent choice for bearings, bushings and other wear items.

Fluorosint 207

Although similar to the 500 grade, Fluorosint 207 has a lower mica fill level. The result is a more ductile material but a higher coefficient of thermal expansion. Fluorosint 207 is comparable to 25% glass filled Teflon with the benefit of being stronger and less abrasive. It is stable to 550F and thus is very good in hot air and steam applications.
