Chemical resistance parallels PTFE   Compared to PTFE:
Continuous use temperatures to 500°F (260°C)   - 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 - has nine times greater resistance to deformation under load than unfilled PTFE. 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. Fluorosint® 500 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 - has unmatched dimensional stability, excellent creep resistance and white color uniquely position this material to serve FDA regulated applications. Fluorosint® 207 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 - FDA compliant Fluorosint HPV PTFE is a high performance bearing grade of Fluorosint - optimized for high PV and very low "K" or wear factor.  Fluorosint HPV PTFE 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 - PTFE is an extreme grade developed specifically for applications where the benefits of PTFE-based materials also require strength, stiffness and stability.  Fluorosint MT-01 PTFE 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.

Fluorosint® 135 PTFE - material designed to provide the lowest coefficient of friction and deformation for seals, bearings, and washer applications. Designed to improve the performance of compressor piston rings, rider bands, and packaging sets, Fluorosint 135's extremely competitive pricing allows companies to guard against expensive equipment failure and ensure maximum production, longevity, and profitability.

Proven applications include:

  • Labyrinth seals and shrouds for turbomachining
  • Dishwasher arm bearing
  • Transmission and power steering seal rings for automobiles
  • Valve seats


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).
