Description

Graphite foil is an excellent sealing material for high temperature, high-pressure transfer ofliquids, gases, steam, chemicals and corrosives. It is manufactured from high purity, highcrystalline natural graphite flakes, which are processed into continuous foil by a special acidand thermal treatment to produce expanded graphite crystals. The expanded graphitecrystals are then formed into foil through an extensive calendaring process withoutany resins and binders.?Advantages of HPMS Graphite 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 strongoxidizers 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 verydifferent 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.Typical Properties of HPMS Graphite FoilITEMUNITVALUEThickness (Roll)inch0.006 - 0.06Thickness (Sheet)inch0.06 - 0.24Widthinch4 - 60Lengthfeet100 - 1000(1)?Excellent Quality: Quality control starts with strict standards for the selection of the flake?graphite, which is a critical element for the quality of the final product,
