FLUOROSINT® - The most dimensionally stable PTFE-Based Product

Fluorosint's unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to PTFE. This bonding results in properties not normally attainable in reinforced PTFE. Fluorosint grades offer an excellent combination of low frictional properties and dimensional stability.

Fluorosint 500 & 207

  • Chemical resistance parallels PTFE
  • Continuous use temperatures to 500°F (260°C)
  • Compared to other PTFE-based products:
    • Higher load carrying capability
    • 1/9 of the deformation under the load
    • Lower coefficient of thermal expansion

Fluorosint 500

Fluorosint 500 has nine times greater resistance to deformation under load than unfilled PTFE. Its coefficient of linear thermal expansion approaches the expansion rate of aluminum and is 1/5 that of PTFE-often eliminating fit and clearance problems. It is 1/3 harder than PTFE, has better wear characteristics and maintains low frictional properties. Fluorosint 500 is also non-abrasive to most mating materials.


Fluorosint 207

Fluorosint 207's unmatched dimensional stability, excellent creep resistance and white color uniquely position this material to serve FDA regulated applications. It is non-permeable in steam and complies with the FDA's regulation 21 CFR 175.300. Its relative wear rate is 1/20 the rate of PTFE below 300°F (150°C).
