Product Description




Expandable graphite is a high-quality natural phosphorus flake graphite produced by our company, which is a flexible graphite product obtained through special modification treatment. It is an ideal new sealing material and widely used in dynamic and static sealing in industries such as petroleum, chemical, electrical, aviation, automotive, shipbuilding, and instrumentation. 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.
