Expandable Graphite
1.Introduction
Expandable graphite is also called flexible graphite. It is made from natural flake graphite, which undergoes instantaneous treatment at high temperature, and the scale becomes worm-like. The volume can expand 100-400 times. This expanded graphite still retains the properties of natural graphite, and has good molding plasticity, flexibility, ductility and sealability. It is an ideal new type of sealing material and a high-quality raw material for various graphite plates.
