Definition:

Expandable flake graphite, also known as intumescent flake graphite, or simply "expandable flake", is a form of intercalated graphite. Intercalation is a process whereby an intercallant material is inserted between the graphene layers of a graphite crystal or particle.This material is manufactured by treating highly crystalline natural flake graphite with a mixture of sulfuric acid and certain other oxidizing agents which aid in "catalysis" of the sulfate intercalation.

Application:

The resultant product is a highly intumescent form of graphite that has proven useful in applications that include fire retardants, high performance gaskets, conductive fillers, electromagnetic pulse and radiation shielding, foundry products, fire collars, construction industries,and many others.
