Products Description

Flexible graphite sheet, graphite foil, graphite paper, graphite tape, and graphite strip (paper) all belong to the category of flexible graphite materials.
Such materials, sometimes called flexible graphite paper or sheet, are obtained by subjecting natural graphite flakes to chemical treatment and subsequent high - temperature heating to form graphite worms. This worm - like graphite powder possesses a density of roughly 0.003g/cc. Subsequently, rolling is employed to form the flexible graphite coil. The expanded graphite coiled material is free of binders and fillers, thus featuring high purity. It demonstrates remarkable corrosion resistance, radioactivity resistance, high / low - temperature resistance, excellent compression resilience, self - lubrication, and impermeability, making it ideal for sealing low - pressure parts. The graphite coil can be combined with metal sheets to produce various types of graphite composite plates.

Regarding product applications:

  1. It can act as a material for graphite packing rings.
  2. It may be integrated with metal sheets to form graphite composite sheets, which are then cut into sealing gaskets of diverse shapes.
  3. After being processed into thick plates, it is directly utilized to fabricate various low - pressure gaskets or high - temperature insulation pads.

Typical specifications for graphite sheets are as follows: Widths of 1000mm or 1500mm, coil lengths of 30m, 50m, or 80m; plate dimensions 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 tailored to meet customer demands.
