GRAFGUARD Expandable Graphite, provides up to 250 times its original volume, when heated to 600 °C (1100 °F). Primarily used as a fire retardant additive, the various grades of GRAFGUARD Expandable Graphite can provide performance tailored to applications. GRAFGUARD Expandable Graphite is commonly used in construction and building materials including wood, foam, and plastics.
When installed as a vessel lining, graphite provides inertness to chemical attack, resistance to abrasion and a heat barrier to protect the vessel itself.
