Fluorosint®
Fluorosint's unique properties are the result of a
proprietary process in which synthetically manufactured
mica is chemically linked to 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
Fluorosint 500 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 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 the FDA's
regulation 21 CFR 175.300. It's relative wear rate is
1/20 the rate of PTFE below 300°F (150°C).

Engineering
Notes:
Due to its PTFE matrix, Fluorosint's physical strength
characteristics are not as high as other advanced engineering
plastics profiled in this guide (i.e. Ketron™, PEEK,
Torlon* PAI).
