Fluorosint® Key Properties By Grade
Fluorosint® 135 grade is a 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.
Fluorosint® 207 grade is the lowest coefficient of friction of Fluorosint grades offering 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 virgin PTFE below 300°F (150°C) making it an excellent choice for aggressive service bearings and bushings.
Fluorosint® 500 grade 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 virgin PTFE -- often eliminating fit and clearance problems. It is 1/3 harder than virgin PTFE, has better wear characteristics and maintains low frictional properties. Fluorosint® 500 PTFE is also non-abrasive to most mating materials.
Fluorosint® HPV grade is the most wear resistant Fluorosint grade and is FDA compliant. Fluorosint HPV PTFE was developed for bearing applications to replace other PTFE formulations that exhibit premature wear. 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 grade is an extreme grade with a continuous use temp of 600F it was developed specifically for applications where the benefits of PTFE-based materials also require strength, stiffness and stability at higher temperatures. 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.
Note: Due to its unique PTFE matrix, Fluorosint's physical strength characteristics are not as high as other advanced engineering plastics profiled here such as Ketron® PEEK or Duratron® T PAI (formerly Torlon PAI). This compliance/ductility makes it ideal for seats and seals.
