Expandable Graphite POWDER

Expandable graphite powder is a unique form of natural graphite that can expand and increase in volume when exposed to high temperatures. This expansion occurs due to the intercalation of gas between the graphite layers, resulting in the formation of worm-like structures. The product is widely used in various applications, including flame retardants, thermal insulation, gaskets, seals, and other industrial purposes.

Flame Retardants: Used in plastics, textiles, foams, and coatings to enhance fire resistance.
Thermal Insulation: Applied in construction materials, gaskets, and seals to improve thermal insulation properties.
Battery Industry: Utilized as a conductive additive in lithium-ion batteries.
Carbon Brushes: Incorporated into carbon brushes for electrical equipment.
Lubricants: Used as a dry lubricant in certain applications.
Expanded Graphite Sheets: Manufacture of flexible graphite sheets.
Conductive Polymers: Incorporated into conductive polymer composites.
Chemical Industry: Used as a catalyst support or in gas storage applications.
Foundry and Metallurgy: As a recarburizer in steel and iron foundries.
