Expandable graphite, also called flexible graphite, it made from high quality natural flake graphite by chemical treatment.
The material has the characteristics of high temperatyre resisitance, thermal conductivity, lubricity, stable chemistry, heat shock resistance etc.
It can be used for making sealing material, wear resisting material, anti-corrosion material, fire proof material, heat insulation material and so on.
Fixed carbon: >= 99%
Expansion at 900 deg. C: 200
Ash at 950 deg. C: <=1%
Moisture at 110 deg. C: <=0.5%
