Expanded graphite
Product Overview
Expanded Graphite Powder (EGP) is a new type of functional carbon material obtained from natural graphite scales through chemical or physical intercalation, washing, drying, high temperature expansion and other processes. It presents a loose and porous worm-like form, but in order to facilitate the storage and transport, the product has been crushed by the crushing process, presenting a lamellar structure, which will be more convenient to use. The preparation methods of expanded graphite powder mainly include chemical intercalation method, electrochemical method, ultrasonic oxidation method, gas phase diffusion method and molten salt method. Among them, chemical intercalation method is one of the most commonly used methods, which is acidified by mixing graphite with concentrated sulfuric acid, concentrated nitric acid and other chemical reagents, and then produced expanded graphite powder after washing, drying and high-temperature expansion and other steps.

Product Features
Adsorption: Due to its rich pore structure, expanded graphite powder has strong adsorption capacity for oil, organic molecules and hydrophobic substances, and is an excellent adsorbent.
High and low temperature resistance: Expanded graphite powder can maintain stable performance under extreme high or low temperature conditions, with excellent resistance to high and low temperature characteristics.
Corrosion resistance: It has good corrosion resistance to many kinds of chemical substances and can be used in harsh chemical environments.
Flexibility and plasticity: Expanded graphite becomes soft and easy to shape, and can be processed into various shapes and sizes.
Application Fields
Sealing material: Expanded graphite powder has excellent sealing performance and can be used to make various sealing elements and gaskets, which are widely used in aerospace, machinery, electronics, nuclear energy, petrochemicals, electric power, shipping, smelting and other industries.
Environmental protection: Due to its strong adsorption capacity for oil substances, expanded graphite powder is widely used in the removal of oil pollution from water surface and the treatment of chemical wastewater.
Biomedicine: Expanded graphite powder has adsorption properties for organic and biological macromolecules, so it has a wide range of application prospects in biomedical materials.
High-energy battery material: Expanded graphite powder can be used as a battery material, using its interlayer reaction of free energy changes into electricity.
