50 mesh high carbon expandable graphite
Expandable graphite is a kind of graphite product which takes natural flake graphite as raw material and is treated by chemical or electro-chemical technology. When it is under high temperature, it can expand 150-400 times in volume instantaneously, flake graphite becomes vermiform graphite which is loose in structure, porous, curved, with large surface area, high surface energy and strong absorptive power. The vermiform graphite pieces can be inlaid by themselves. In this way, its flexibility, resilience and plasticity are increased. It is a high-quality material for making flexible graphite sheets and various sealing components. Except has the excellent properties such as cold and heat resistance, corrosion resistance, self lubrication, etc, expandable graphite also has the properties such as softness, compression resilience, adsorption, ecological environment compatibility, bio compatibility and radiation resistance and other characteristics.
