Graphite paper

　　Flexible Graphite Sheet is manufactured through a process involving chemical intercalation, high-temperature expansion, and precision calendering of high-purity natural flake graphite. It contains no binders whatsoever and boasts exceptional properties including superior high-temperature resistance, chemical stability, thermal and electrical conductivity, and flexible sealing performance.

　　The product can operate reliably over an extended period under extreme temperatures ranging from -200°C to +3000°C (in an inert atmosphere). It exhibits excellent resistance to corrosion by acids, bases, solvents, and reducing atmospheres, while also boasting low thermal resistance, high resilience, and superior creep resistance. Its natural layered structure endows the material with exceptional conformability, enabling it to effectively fill uneven surfaces and achieve reliable sealing.

Typical application areas:

Conductive sealing rings/gaskets for high-temperature furnace equipment (such as continuous firing furnaces and graphitization furnaces)

Bipolar plates and current collectors in lithium batteries and fuel cells

Thermal dissipation film for electronic devices (can be laminated with metal foil to enhance thermal conductivity)

Static seals (such as flanges, valves, and pumps) in the chemical, power, and aerospace industries.

We offer a wide range of densities (0.5–1.8 g/cm³) and thicknesses (0.03–3.0 mm), and provide customized solutions to meet your diverse needs in demanding operating conditions.

Highly Thermally Conductive Flexible Graphite Paper—A Highly Efficient Planar Cooling Solution for Smart Home Appliances and Electronic Devices

　　Today, as 5G terminals, ultra-thin laptops, Mini LED TVs, high-end routers, smart speakers, and other devices continue to evolve toward lighter, thinner designs with higher performance and greater integration, localized hotspots and limited cooling space have become common challenges across the industry. TaiXing’s High-Thermal-Conductivity Flexible Graphite Sheet, with its outstanding in-plane thermal conductivity and ultra-thin, flexible characteristics, has emerged as an ideal material for planar, uniform-temperature heat dissipation in next-generation electronic devices.

Core Advantages

Ultra-high in-plane thermal conductivity: up to 500–600 W/m·K, enabling rapid lateral heat diffusion across chips, modules, and panels and eliminating localized hotspots.

Ultra-thin and lightweight: only 0.03–0.2 mm thick, lightweight, and does not add extra burden to the device—perfectly suited for ultra-thin structures.

Exceptional flexibility: Bendable, rollable, and adaptable to 3D curved surfaces, allowing for easy integration into tight or oddly shaped spaces.

Electromagnetic shielding assistive function: The natural graphite structure possesses a certain EMI suppression capability, enhancing the overall signal stability of the device.

Environmentally friendly and reliable: Halogen-free and heavy-metal-free, certified by RoHS and REACH. It remains stable and does not leach out even after prolonged use.
