Material Description

Fluorosint® is a proprietary mixture in which synthetically manufactured mica is chemically linked to polytetrafluoroethylene (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.  It offers excellent chemical resistance and continuous use temperature of 500°F (260 °C).  Compared with PTFE, it has higher load carrying capability, 1/9th of the deformation under load, and a lower coefficient of thermal expansion.

Grades of Fluorosint®

Fluorosint® 500

Fluorosint® 500 has nine times greater resistance to deformation under load than unfilled PTFE.  Its coefficient of linear thermal expansion (CLTE) approaches the expansion rate of aluminum and is 1/5th that of PTFE — often eliminating fit and clearance problems. It is 1/3rd 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 FDA regulation 21 CFR 175.300.  Its relative wear rate is 1/20th the rate of PTFE below 300°F (150°C).
