[ NATURAL GRAPHITE ]
Expandable graphite
Intercalated natural graphite that expands with heat. Feedstock for expanded graphite and intumescent systems.
| Physical and mechanical properties | Value |
|---|---|
| Expansion | 150–350 ml/g |
| Onset temperature | 150–220°C |
| Base | Intercalated crystalline graphite |
Applications
Fire protection
Intumescent gaskets
Compounds
Flexible sheet feedstock
Natural flake graphite treated by chemical intercalation. When heated it expands sharply (intumescent effect). It is the precursor of expanded graphite and flexible graphite.
Do not confuse it with already expanded graphite or with laminated sheet (geometry / product).
