You've Heard of PTFE, But Have You Heard of Fluorosint®?



You may have heard of PTFE, but have you heard of Fluorosint®, Quadrant’s “PTFE with Muscles”?

Fluorosint® is a range of enhanced PTFE materials developed by Quadrant EPP to fill the performance gaps where unfilled and low-tech, filled PTFE based polymers underperform. Each Fluorosint® material was specifically developed to excel in demanding bearing and seal applications.

Under extreme pressure and temperatures, some polymers are subject to deformation, commonly referred to as “creep.” Creep occurs particularly with Polytetrafluoroethylene (PTFE). While virgin PFTE has excellent chemical resistance, dielectric strength, the lowest COF of any solid, and a wide temperature range (-450 F to +500 F), it cannot be cross-linked like an elastomer, meaning the material has no memory and can experience creep.

To mitigate creep, many material producers began creating filled versions of PTFE. Typical fillers include bronze, glass, molybdenum disulfide, stainless steel, and graphite. While these fillers do improve creep resistance (to some extent), filled PTFE can present other issues—including abrasiveness to mating materials, contamination to clean requirements, and altering the dielectric strength of the base polymer.

Quadrant has developed a solution to this problem with their series of Fluorosint® materials which are used for some of the most demanding and critical applications across numerous industries. Quadrant uses a proprietary process in which synthetically manufactured mica is chemically linked to the PTFE. This bonding process creates a polymer that has excellent dimensional stability and resistance to deformation under load while still maintaining the very low frictional properties that industries have come to expect of a PTFE-based material.


Material Characteristics

Excellent chemical and Hydrolosis resistance

High maximum allowable service temperature in air (260 °C continuously)

Excellent weather and UV resistance

Good electrical insulating properties

Inherent low flammability

Physiologically inert meaning some grades are suitable for food contact (not Fluorosint 500 or MT-01)


Quadrant’s Fluorosint® family of materials are an ideal way to gain deformation resistance and stability while still maintaining a very slick, low coefficient of friction and wear performance of a PTFE-based material:

Fluorosint® 135 – Offering the lowest wear rate and extremely chemically inert. Applications include compressor piston rings, pump and valve wear parts, seals, bearings, thrust washers, rider bands, and packing sets.

Fluorosint® 207 – An FDA-compliant version offering excellent creep resistance and a very low coefficient of friction. Applications include seals, mixers, pumps, appliances, bearings, and valve seals.

Fluorosint® 500 – Featuring nine times greater resistance to deformation under load than an unfilled PTFE. The high level of mica used in this grade makes it an effective replacement for traditional metal (high pressure) seals and wear parts.

Fluorosint® HPV – An FDA-compliant material optimized for high PV conditions while offering very low “K” wear factor. Ideal for high performance bearings, bushings, and seals where higher loads and minimal wear is required.

Fluorosint® MT-01 – Quadrant’s most extreme grade of material, delivering performance at elevated temperatures for aggressive service components where strength and stability are expected.
