Material Description

PTFE has unusually high thermal stability and chemical resistance. It additionally has excellent sliding properties, very good electrical resistance and a non-stick surface. However, it also exhibits low mechanical strength and rigidity, meaning that its use is specific to applications that make use of its thermal and wear based properties.

PTFE can be supplied in rods and sheets, and is used for sliding applications, particularly in environments that will expose the part to chemical stress.

Specialist Grades of Nylon PTFE

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.
