Expandable graphite is a high-performance carbon material that expands under heat, forming a flexible and fire-resistant protective layer. Manufactured through chemical intercalation processes, this material offers exceptional thermal stability, electrical conductivity, and structural integrity. It is widely used in flame-retardant coatings, thermal management systems, battery electrodes, and high-temperature industrial applications, ensuring reliable performance in demanding environments requiring advanced insulation and fireproofing.
Product Overview
Expandable graphite is produced by chemically treating natural flake graphite and subjecting it to high-temperature expansion, transforming it into a graphite "worm" material that can expand 100-600 times its original volume. This material possesses lightweight properties, excellent electrical and thermal conductivity, high-temperature resistance, and strong resistance to acid and alkali corrosion. Expandable graphite also exhibits great rebound resilience, lubrication, plasticity, and exceptional chemical stability, making it suitable for a wide range of industrial and technological applications.
