Expandable graphite
Expandable graphite undergoes instantaneous treatment at high temperature, the flake becomes worm-like, and the volume can expand by 100-400 times. This expanded graphite still maintains the properties of natural graphite and has good molding plasticity, flexible ductility and sealability. A variety of high-quality raw materials for graphite sheets and seals can also be used as a new type of protective slag and heating agent in the metallurgical industry
