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 ® HPV
Most Wear-Resistant Fluorosint Grade
FDA-compliant Fluorosint ® HPV is a high performance bearing grade of Fluorosint -- optimized for high PV and very low "K", or wear factor. Fluorosint HPV was developed for bearing applications where other, low-tech PTFE formulations exhibit premature wear or simply cannot perform. FDA compliance gives food and pharmaceutical equipment manufacturers new design options and all benefit from its excellent load bearing and wear characteristics.
COMMON APPLICATIONS
- Bearings
- Commercial food equipment
- Wear guides
- High performance seals
- Thrust washers
