Flexible graphite paper is a layered material produced from high-carbon flake graphite through chemical treatment, high-temperature expansion, and rolling. It possesses excellent properties, including high-temperature resistance, corrosion resistance, high thermal conductivity, good flexibility, and self-lubricating characteristics. These attributes make it widely applicable across various fields, such as industry, electronics, and scientific research.
1. Industrial Sealing Sector
Flexible graphite paper serves as a foundational material for manufacturing various graphite sealing components, including packing rings, gland packing, gaskets, and composite sheets.
Application Areas: Petrochemical, power generation, machinery, metallurgy, nuclear energy, and other industries.
Advantages: Resistance to high and low temperatures (-200°C to 650°C; up to 3000°C in non-oxidizing media), corrosion resistance, excellent sealing performance, wear resistance, and the flexibility to conform to various surfaces.
Typical Uses: Dynamic and static sealing for equipment such as pumps, valves, pipelines, and compressors; serves as a replacement for traditional sealing materials like rubber and asbestos.

Typical Uses: Dynamic and static sealing for equipment such as pumps, valves, pipelines, and compressors; it serves as a replacement for traditional sealing materials like rubber or asbestos.
2. Electronic Thermal Management
Leveraging its high thermal conductivity (in-plane thermal conductivity can reach 1500 W/mK—40% lower density than aluminum and 20% lower than copper) and lightweight nature (30% lighter than aluminum), flexible graphite paper is extensively used for heat dissipation in electronic devices:
Application Scenarios: Laptops, tablets, mobile phones, digital cameras, and LED lighting.
Function: Distributes heat evenly, eliminates "hot spots," shields heat sources, and enhances device performance.
Form: Ultra-thin graphite paper (0.05–1.5 mm) can be die-cut into heat-dissipating components that conform to both flat and curved surfaces.
3. Other Special Applications
Wet Braking and Transmission: Used as a friction material in automatic transmissions to regulate dynamic and static friction coefficients, thereby enhancing operational smoothness and safety.
Semiconductors and Metallurgy: Leverages properties such as electrical conductivity, high-temperature resistance, and resistance to acid/alkali corrosion for use in electrodes and conductive components.
