Product Profile:
- Chemical resistance parallels PTFE
- Continuous use temperatures to 500°F (260°C)
- Compared to PTFE
- higher load carrying capability
- 1/9 of the deformation under load
- lower coefficient of thermal expansion
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
Exceptional Dimensional Stability for Precise Tolerance Control
Fluorosint® 500 has nine times greater resistance to deformation under load than unfilled PTFE (see Figure 19). 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 (see Figure 20). 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
Lowest Coefficient of Friction of Fluorosint Grades
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) making it an excellent choice for aggressive service bearings and bushings.
Fluorosint® HPV
Most Wear Resistant Fluorosint Grade - Outlasts Low-tech PTFE Based Materials
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.
Fluorosint® MT-01
Ultra-High Performance Grade For Stability At Elevated Temperature
Fluorosint MT-01 is an extreme grade developed specifically for applications where the benefits of PTFE-based materials also require strength, stiffness and stability. Fluorosint MT-01 delivers high mechanical performance at elevated temperature and as a result is often specified in seat, seal and wear applications where extreme conditions are present.

Engineering Notes
Due to its PTFE matrix, Fluorosint's physical strength
characteristics are not as high as other advanced engineering plastics profiled in this guide (i.e.,
Ketron® PEEK, Torlon® PAI)
