• Description:

　　Expandable graphite is a kind of graphite product obtained from high-quality natural flake graphite after special modification treatment. After high temperature transient treatment, it changes from flake shape to worm shape, and the volume expands 100-400 times. This kind of expanded graphite still maintains the properties of natural graphite, and has good molding plasticity, flexibility, ductility and sealing. It is a variety of graphite sheets , High-quality raw materials for seals, can also be used as a new type of protective slag, heating agent in the metallurgical industry, and flame-retardant materials for the fire department. It is widely used in steel, metallurgy, petroleum, chemical, machinery, aerospace, atomic energy, fire and flame retardant, military and other industrial sectors.
