Expandable Graphite F.C 99%min For Flame Retardants
Expandable graphite is a synthesized intercalation compound of
graphite that expands or exfoliates when heated. Once heated, it
results an increase in the volume of up to 400 times, a lowering of
bulk density, and approximately a 10-fold increase in surface area.
Then it’s compressed into a highly cohesive flexible sheet.
Another principal application is as a flame retardant. As a result
of the heat of a fire the graphite expands and creates an
intumescent layer on the surface of the material. This retards the
spread of fire and minimizes one of the most harmful effects of
combustion: the creation of toxic gases and fumes.
Benefits of expandable graphite as flame retardant:
1.Forms an intumescence layer with Thermal Radiation Shielding, with
superior Heat Diffusion.
2.Stops or slows the spread of fire and toxic gases.
3.Easy to apply, cost Effective, satisfied performance with low
adding levels.
4.Non-toxic, non-halogenated fire-stop additive.
5.Neutral surface pH makes compatible with any catalyst system.
