Flexible graphite sheet, graphite foil, graphite paper, graphite
tape, and graphite strip (paper) all fall under the category of
flexible graphite materials. These materials, occasionally called
flexible graphite paper or sheet, are created by chemically
treating natural graphite flakes and then heating them at high
temperatures to form graphite worms. The density of this worm -
like graphite powder is around 0.003g/cc. Subsequently, rolling is
utilized to shape the flexible graphite coil. The expanded graphite
coiled material contains no binders or fillers, hence boasting high
purity. It exhibits excellent corrosion resistance, radioactivity
resistance, high / low - temperature resistance, good compression
resilience, self - lubrication, and impermeability, making it a
great fit for sealing low - pressure components. The graphite coil
can be combined with metal sheets to produce various graphite
composite plates.
In terms of product applications:
- It can serve as a material for graphite packing rings.
- It may be combined with metal sheets to form graphite composite
sheets, which are then cut into sealing gaskets of various shapes.
- After being processed into thick plates, it is directly used to
fabricate various low - pressure gaskets or high - temperature
insulation pads.
Standard specifications for graphite sheets are as follows: Widths
of 1000mm or 1500mm, coil lengths of 30m, 50m, or 80m; plate sizes
of 1000mm or 1500mm; coil thicknesses ranging from 0.15 - 1.0mm;
plate thicknesses from 1.0mm - 5mm; density values between 0.8 -
1.25g/cm3. Other special specifications can be adjusted to meet
customer demands.
