| 2. Description
|
|
|
| Expandable graphite powders
are made from natural flake graphite treated by chemical or electro-chemical
processes. They can expand 150-250 times in volume at high temperature
with large surface area, high surface energy, good flexibility, resilience
and plasticity etc. |

elasticity and plasticity |
|
High resistance to corrosion, radiation,
extremely high and low temperature |
|
High resistance to temperature shock |
|
High thermal conductivity and electric
conductivity |
|
Anti-aging |
