Flexible Graphite Foil/Roll/Sheet is an excellent sealing material for high temperature, high-pressure transfer of liquids, gases, steam, chemicals and corrosives. It is manufactured from high purity, high crystalline natural graphite flakes, which are processed into continuous foil by a special acid
and thermal treatment to produce expanded graphite crystals. The expanded graphite crystals are then formed into foil through an extensive calendaring process without any resins and binders.
Advantages of Flexible Graphite Sheet/Roll/Foil
- Excellent thermal stability and reflectivity.
- Resistant to low temperature of -200 °C.
- Resistant to high temperature of 450 °C in air, 700 °C in steam and 3000 °C in inert or reducing environment.
- Chemically inert: Resistant to fluids with pH range of 0-14 (except strong
oxidizers such as nitric or sulphuric acid).
- High purity: eliminates potential fluid contamination, ideal material for nuclear applications
- Low coefficient of friction: It is self-lubricating.
- Asbestos free: no associated health hazards.
- Low electrical resistivity.
- High thermal conductivity.
- Highly anisotropic: the electrical and thermal conductivity characteristics are very
different in the direction parallel to and perpendicular to flakes.
- Excellent in-process longevity: save replacement and down time costs.
Applications
- Gaskets material in automotive, petroleum and chemical, paper, and nuclear industries.
- Thermal barrier at high temperature to provide outstanding reflectivity.
- Fuel cell industry for bipolar plates.
- Excellent for sealing high temperature valves, shafts and flanges.
- Excellent linings and protective layer for vessels containing hot or corrosive fluids. |
