Fluorosint® (PTFE + MICA)
Fluorosint®’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 300°F (150°C).
Fluorosint®'s unique properties are the result of a proprietary process
in which synthetically manufactured mica is chemically linked to PTFE.
This bonding results into a load carrying capability and thermal
expansion rate not normally attainable in reinforced PTFE. The chemical
and temperature resistance inherent in PTFE are practically retained.
Fluorosint® 500 has nine times greater resistance to
deformation under load than unfilled PTFE (tested according to ASTM D
621; stress of 14 MPa of 50°C). Its coefficient of linear thermal
expansion approaches the expansion rate of aluminum and is 1/5 that of
virgin PTFE. It is considerably harder than virgin PTFE, has better wear
characteristics and maintains low frictional properties. Fluorosint® 500
is also non-abrasive to most mating materials.
Fluorosint® 207's raw material composition used for
it's production is suited for food contact according to the EU/FDA
regulations. In combination with a good mechanical performance and an
inherent outstanding chemical and hydrolysis resistance, this feature
opens numerous application possibilities in food, pharmaceutical and
medical industries.
