Expandable Graphite

Expandable graphite is produced using a chemical process: Foreign molecules are intercalated between the graphite's graphene layers. This "intercalated" graphite is called expandable graphite. If expanded graphite is exposed to high temperatures, the embedded foreign molecules are suddenly expelled, the graphene layers are greatly expanded and so-called expanded graphite is produced.  If the expanded graphite is pressed, foils, sheets, packings etc. can be produced. These are mainly used as seals, but also as electrical and thermal conductive foils. Unexpanded graphite is often used for flame protection. If expanded graphite is heated to a high temperature, it expands considerably. It forms a protective and gas-impermeable layer on the hot surface and thus prevents the flames from spreading. Expandable graphite is used as a non-toxic and halogen-free flame retardant, e.g. in PU foams (e.g. mattresses in hospitals), in special coatings and other flame retardant systems.
