Flexible graphite materials, including flexible graphite sheets, graphite foils, graphite papers, graphite tapes, and graphite strips (papers), are crafted through a specific process. Natural graphite flakes undergo chemical treatment and are then heated at high temperatures to create graphite worms. The density of this worm - like graphite powder is approximately 0.003g/cc. Subsequently, rolling is carried out to form flexible graphite coils.
These expanded graphite coils are free of binders and fillers, endowing them with high purity. They also exhibit excellent corrosion resistance, radioactivity resistance, high and low - temperature resistance, good compression resilience, self - lubrication, and impermeability. As such, they are well - suited for sealing low - pressure components. Moreover, graphite coils can be compounded with metal sheets to produce various types of graphite composite plates.
Product Applications:
- Serve as materials for graphite packing rings.
- Combine with metal sheets to form graphite composite sheets, which can then be cut into sealing gaskets of diverse shapes.
- After being processed into thick plates, they are directly used to manufacture various low - pressure gaskets or high - temperature insulation pads.
Common Specifications for Graphite Sheets:
Width: 1000mm or 1500mm; Coil Length: 30m, 50m, or 80m; Plate Size: 1000mm or 1500mm; Coil Thickness: 0.15 - 1.0mm; Plate Thickness: 1.0 - 5mm; Density: 0.8 - 1.25g/cm³. Special specifications can be customized according to customer requests.
