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.
