Fluorosint® Enhanced PTFE
Fluorosint® Enhanced PTFE [PTFE; colours: white, ivory, tan, dark-grey]
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
-
Labyrinth 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) -
Transmission 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
-
Dishwasher Arm Bearing
These bearings made of Fluorosint® 207 PTFE offer a 20 year service life, and FDA compliance. (Prior material PTFE) -
Valve 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.

Coefficients 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.
