Applications
The best expanded graphite solution in high pressure and high temperature applications. Resistant to organic, inorganic acids, solvents, hot wax and oils. Impermeable to gases and fluids, corrosion resistant, excellent for sealing high temperature valves, shafts, and flanges, high thermal conductivity. Exceptions are strong oxidizing compounds such as concentrated nitric acids, high concentrated sulphuric acids, chromium (VI) and permanganate solutions, chloric acid and molten alkaline and alkaline earth metals. Available in 1 meter square sheets |
|
Physical properties are based on
a 2 mm thick
sample.
As in all compressed sheets the P x T values decrease significantly as the thickness increases. Our maximum temperature, pressure and P x T values cannot be exceeded. |
