Fluorosint ® (Filled PTFE) Specifications
DESCRIPTION
 Fluorosint ® is a proprietary mixture in which
synthetically manufactured mica is chemically linked to
PolyTetraFluoroEthylene (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 ®
is produced only by Quadrant DSM Engineering Plastic Products.
Fluorosint ® offers excellent chemical resistance
and continuous use temperature of 500°F (260 °C). Compared with PTFE, it has
higher load carrying capability, 1/9 of the deformation under load, and a
lower coefficient of thermal expansion.
FLUOROSINT GRADES
Fluorosint ® 500
Fluorosint ® 500 has nine times greater resistance
to deformation under load than unfilled PTFE. Its coefficient of linear
thermal expansion (CLTE) approaches the expansion rate of aluminum and is
1/5 that of PTFE -- often eliminating fit and clearance problems. It is 1/3
harder than PTFE, has better wear characteristics, and maintains low
frictional properties. Fluorosint ® 500 is also
non-abrasive to most mating materials.
Fluorosint ® 207
Fluorosint ® 207'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 FDA regulation 21 CFR 175.300. It's relative wear rate is
1/20 the rate of PTFE below 300°F (150°C).
