Expanded Graphite (EG)

Expanded graphite (EG) is obtained by treating high-quality natural flake graphite with strong acids and strong oxidants for interlayering. Expanded graphite also inherits the properties of natural flake graphite, featuring extremely high electrical conductivity, high temperature resistance, corrosion resistance, and radiation resistance. Compared with natural flake graphite, expanded graphite has a loose and porous structure, is flexible and bendable, has a lower density, a larger volume and surface area, and a higher surface energy. It also possesses extremely strong seismic resistance, torsional resistance, pressure resistance, and adsorption capacity. It is widely used in the production of flame-retardant and fire-resistant materials, sealing materials, environmentally friendly adsorption materials, battery materials, etc.

Remark: The expansion Ratio (ER) can be customized.

Advantages:

- Lightweight and soft: Low density (0.8 - 1.8 g/cm³), soft texture that can be compressed, with excellent elasticity recovery.

- Strong adsorption capacity: The porous structure has outstanding ability to adsorb non-polar substances such as oils.

- Flame-retardant and heat-insulating: When exposed to fire, it rapidly expands to form a dense carbon layer, blocking oxygen and heat, with low smoke and no molten droplets.

- Sealing performance: Low creep, small thermal expansion coefficient, capable of withstanding extreme temperature fluctuations, and is hailed as the "King of Seals".

Applications:

- Sealing Materials: such as sealing packing, gaskets, and graphite packing.

- Flame retardant materials: used in engineering plastics and rubber flame retardant, as well as in the fire as a heat insulation layer

- Environmental protection field: used to remove water surface oil pollution and wastewater treatment

- Biomedicine: such as medical dressing, drug carrier, etc

- High-energy battery materials: can reduce polarization during charging

Remark:

Keep dry when storing to avoid moisture.
