Expandable Graphite Powder

Expandable graphite powder is a kind of graphite product that takes nafural flake graphite as raw material and is treated by chemical or electro -chemical technology. When it is under high temperature, it can expand instantaneously, flake graphite becomes vermiform graphite, which is loose in structure, porous, curved, with larger suface area, high surface energy and strong adsorptive power. In this way, its flexibility, resilience and mach inablility are increased. It is gigh-quality material for making flexible graphite.
It's sheets and various sealing components; It can also be used for heat preservation in metal lurgical industry and as fire-exting uishing agent for fire fighting. The development of low temperature expandable graphite provides new method for the development of fire prevention material.
