Graphite Materials
Natural flake graphite intercalated with sulfuric/nitric complexes; expands 200–450 times original volume when heated above ~150 °C. The resulting intumescent char acts as a heat, oxygen and smoke barrier, providing a halogen-free route to fire-retardant formulations.
Features
Fast onset expansion – begins to intumesce at 150–180 °C
High expansion ratio – forms thick insulating layer within seconds
Halogen-free – low smoke and non-corrosive gas emission
Post-treatable – acid level can be reduced for pH-sensitive systems
Industrial Applications
Construction
Fire-stop sealants, intumescent strips, gypsum boards
Automotive
Flame shields and gaskets around battery packs
General Industrials
Additive for fire-retarded foams, cables and coatings
