Highly Conductive Expanded Graphite Micron Powder
Purity: ≥ 96%, Size: 70 µm
Expanded graphite powder is produced from natural flake graphite through chemical or electrochemical expansion. It retains the inherent advantages of crystalline graphite—excellent high-temperature resistance, corrosion resistance, lubricity, and chemical stability—while offering dramatically increased electrical and thermal conductivity.
This makes it a superior conductive additive across many industrial applications requiring enhanced heat dissipation or electrical performance.
