Expandable Graphite

Also known as “intumescent flake graphite,” expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated. If exposed to a rapid increase in temperature, these intercalation compounds decompose into gaseous products, which results in high inter-graphene layer pressure. This pressure develops enough force to push apart graphite basal planes in the “c” axis direction.  Cuspress’s expandable graphite is used as a fire suppressant intumescent additive, as a raw material to manufacture graphite gasket products, as an electrically conductive filler, as a foundry additive, and in a wide variety of other industrial applications.
