Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated. This material is manufactured by treating flake graphite with various intercalation reagents that migrate between the graphene layers in a graphite crystal and remain as stable species.

Expandable graphite flakes are high-carbon intercalation compounds that rapidly expand at temperatures exceeding 200C, making them essential as intumescent fire retardant additives in coatings, sealants, and construction materials. Supplied in mesh sizes from 32 to 100 mesh with carbon purities typically above 90%, these flakes offer superior expansion volumes of 200-350 ml/g. Widely sourced from Chinese and Indian producers, expandable graphite is a critical import commodity for B2B buyers in the coatings, polyurethane, and passive fire protection industries, traded in bulk bags or drums with global logistics availability.
