Fluorosint® Enhanced PTFE

Fluorosint® Enhanced PTFE

Product Overview

  • High maximum allowable service temperature in air (260°C continuously)
  • Excellent chemical and hydrolysis resistance 
  • Outstanding UV- and weather resistance
  • Physiologically inert (suitable for food contact, except Fluorosint 500, Fluorosint MT-01)
  • Inherent low flammability
  • Good electrical insulating properties

Fluorosint enhanced PTFE’s unique properties are the result of a proprietary process in which synthetically manufactured mica is chemically linked to virgin 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 PTFE

Exceptional Dimensional Stability for Precise Tolerance Control

Reinforced with a proprietary synthetic mica, this material exhibits, in addition to its inherent outstanding chemical and hydrolysis resistance, very good mechanical and tribological properties.
Fluorosint 500 PTFE (colour: ivory) 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 considerably harder than virgin PTFE, has better wear characteristics and maintains low frictional properties. Fluorosint 500 PTFE is also non-abrasive to most mating materials.

    Proven Applications

    • keyboard_arrow_downLabyrinth Seals and Shrouds

      Abradable seals in turbomachinery fabricated from Fluorosint® 500 PTFE tubular bar reliably perform in hostile chemical environments while providing dramatic efficiency gains. (Prior materials: Aluminum, Bronze, Babbit)

    • keyboard_arrow_downTransmission and Power Steering Seal Rings

      Europe's premier automobile manufacturers choose Fluorosint® 500 PTFE over other filled PTFE for improved performance and service life capabilities. (Prior material: GF PTFE)

    Fluorosint® 207 PTFE

    Lowest Coefficient of Friction of Fluorosint Grades

    Fluorosint® 207 (colour: white) PTFE'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 150 °C / 300 °F making it an excellent choice for aggressive service bearings and bushings.

      Proven Applications

      • keyboard_arrow_downDishwasher Arm Bearing

        These bearings made of Fluorosint® 207 PTFE offer a 20 year service life, and FDA compliance. (Prior material PTFE)

      • keyboard_arrow_downValve Seats

        Seats fabricated from Fluorosint® 207 PTFE excel in steam and hot air service due to their non-permeability, excellent dimensional stability, and low wear rate. (Prior materials: PTFE, Filled PTFE)

      Fluorosint® HPV PTFE

      Most Wear Resistant Fluorosint Grade - Outlasts Low-tech PTFE Based Materials

      FDA compliant Fluorosint HPV (colour: tan) 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 PTFE (colour: dark-grey) 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

          Superior Performance Grade For Stability In Extreme Conditions

          Fluorosint® 135 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.

            • keyboard_arrow_downCoefficients of Linear Thermal Expansion

            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® PAI (formerly Torlon® PAI). This compliance/ductility makes it ideal for seats and seals.
