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. Fluorosint ® is produced only by Quadrant DSM Engineering Plastic Products.
Fluorosint ® offers excellent chemical resistance and continuous use temperature of 500°F (260 °C). Compared with PTFE, it has higher load carrying capability, 1/9 of the deformation under load, and a lower coefficient of thermal expansion.
FLUOROSINT GRADES 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 1/5 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 FDA regulation 21 CFR 175.300. It's relative wear rate is 1/20 the rate of PTFE below 300°F (150°C).
