Highly Conductive Expanded Graphite Micron Powder

Purity: ≥ 96%, Size: 20 µm

Highly Conductive Expanded Graphite Micron Powder is a high-purity, micron-sized functional carbon additive produced by chemical or electro-chemical expansion of natural flake graphite, enabling uniform dispersion within host matrices while significantly enhancing both thermal and electrical conductivity; it retains the inherent advantages of crystalline graphite such as high temperature stability, corrosion resistance, and self-lubricating behavior, ensuring reliable performance under demanding processing and operating conditions, and provides structural as well as functional benefits in polymers, elastomers, composites, and inorganic systems by improving conductivity without compromising mechanical integrity, offering a cost-effective solution for long-term, high-performance formulations.

Technical Properties

Applications

• Conductive Polymers & Composites: Enhances bulk and surface electrical conductivity, enabling charge dissipation and stable conductive networks without significantly increasing filler loading.
• EMI/RFI Shielding: Improves electromagnetic interference attenuation in housings, enclosures, coatings, and electronic components by forming continuous conductive pathways.
• Thermal Management Systems: Increases thermal conductivity in thermally conductive plastics, heat spreaders, and thermal interface materials to support efficient heat dissipation.
• Energy Storage Devices: Acts as a conductive agent in electrodes for lithium-ion batteries, supercapacitors, and fuel cells, improving electron transport and overall electrochemical efficiency.
• Adhesives & Sealants: Provides thermal and electrical conductivity while maintaining sealing performance in assemblies exposed to heat and vibration.
• Elastomers & Rubber Compounds: Enables antistatic and electrostatic-dissipative (ESD) properties while reinforcing mechanical durability in flexible components.
• Graphite Foil & Sealing Products: Serves as a precursor and functional filler for producing graphite foil, braided packings, and high-temperature sealing materials.
• Lubrication & Tribological Systems: Functions as a solid lubricant, reducing friction and wear in high-load or high-temperature mechanical interfaces.
• Flame-Retardant Materials: Supports char formation and thermal barrier effects when used with flame-retardant additives, improving fire resistance of polymers and foams.
• Foundry & Inorganic Materials: Enhances thermal stability, release behavior, and conductivity in molds and inorganic composite formulations used in casting processes.
