Expandable Graphite

factory2 Expandable Graphite

Expandable graphite is a synthesized intercalation compound of graphite that expands or exfoliates when heated. Upon heating, it increases in volume by up to 400 times, reduces bulk density, and achieves approximately a tenfold increase in surface area. It is then compressed into a highly cohesive, flexible sheet. A key application of expandable graphite is as a flame retardant. When exposed to the heat of a fire, the graphite expands and forms an intumescent layer on the material's surface. This layer slows the spread of fire and reduces one of the most harmful effects of combustion: the generation of toxic gases and fumes.

Benefits of expandable graphite as flame retardant:

  1. Forms an intumescent layer with thermal radiation shielding and
  2. excellent heat diffusion.
  3. Prevents or slows the spread of fire and toxic gases.
  4. Easy to apply, cost-effective, and delivers reliable performance even at low additive levels.
  5. Non-toxic, non-halogenated fire-stop additive
  6. Neutral surface pH, ensuring compatibility with any catalyst system.

Our Expandable Graphite is the right solution for:

  • Graphite Foil, Sheet,Roll, Gaskets;
  • Fire Retardant;
  • Conductive Additive.
