Graphite Flakes/Powder
Expandable graphite powder
Expandable graphite powders are made from natural flake graphite treated by chemical or electro-chemical processes. They can expand 150-250 times in volume at high temperature with large surface area, high surface energy, good flexibility, resilience and plasticity etc.
