GENERAL 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 ® 207
Lowest Coefficient of Friction of Fluorosint Grades
FDA-compliant Fluorosint ® 207 Enhanced PTFE is a significant performance upgrade for any designer using PTFE for applications where temperature resistance, chemical resistance and FDA compliance are all important. Fluorosint 207 lasts far longer than unfilled PTFE in wear applications and has an extremely low coefficient of friction. Fluorosint 207 works well against most mating surfaces.
COMMON APPLICATIONS
- Seals
- Mixers
- Pumps
- Appliances
- Bearings
- Valve seats
