As the interlayer combination of natural flake graphite is
relatively lose, graphite inter-layer compound (Expandable
graphite) can be obtained through chemical treatment or
The expandable graphite is a kind of high-ranking sealing material.
With features of heatproof, abrasive resistance, anticorrosion,
oxidation resistance, great surfactivity and strong adsorbability,
it is a replacement for traditional sealing materials such as
asbestos, rubber and some metallic materials in making various
sealing parts in pump, valve, pressure vessel and pipelines.
With high adsorbability over petroleum product (Such as heavy oil),
expandable graphite is commonly used as new-type sorbent in
environment protection for oil pollution in river, lake, sea and
drinking water source.
