Expandable Graphite Powder JSYA-EG250 is halogen-free intercalated expandable graphite with CAS 7782-42-5, presented as grey flake powder. It is produced by inserting intercalation compounds between graphite crystal layers. When subjected to high temperature, the material rapidly expands to form worm-like porous carbon layer.

For fireproof board applications, JSYA-EG250 is blended into board matrix. In fire scenarios, it expands quickly and forms a dense, heat-insulating carbon barrier. This
