amorphous graphite

Our company is the sole factory who can manufacture the non-sulfur and low sulfur expanded graphite from China.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.
