Expandable Graphite Powder

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 adsorptive 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, it can also be used for heat preservation in metallurgical industry and as fire-extinguishing agent for fire fighting. 

Application:
1.As additive of heat preservation in metallurgy
2.The raw materials of flexible graphite foil
3.Absorbing materials of battery
4.Lubricant and additive materials
5.Fire prevention meterial

Feature:
It can be processed into various products with abilities of heat-insulating, lubricant or bearing the high-temperature, chemical stability because of its excellent expandability.
