The expanded graphite for flexible graphite sheet & roll
Expanded graphite is a type of flexible graphite which takes natural flake graphite as the raw material and is treated by chemical technology. Under the high temperature, it can expanded 100-300 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 powder. The vermiform graphite pieces can be inlaid by themselves. In this way, its flexibility, resilience and plasticity are increased. It is high quality material of making flexible graphite sheet & roll and various sealing components.
