Product Description





Expandable graphite undergoes high-temperature instantaneous treatment, transforming into a worm like flake with a volume that can expand 100-400 times. This type of expanded graphite still retains the properties of natural graphite and has good plasticity, flexibility, ductility, and sealing properties. It is a high-quality raw material for various graphite sheets and seals, and can also be used as a new type of protective slag and heating agent in the metallurgical industry.
