Thermal conductive graphite sheet is a brand-new thermal conductive and heat-dissipating material, with unique grain orientation and uniform thermal conductivity in two directions. The lamellar structure can adapt to any surface well, shielding heat sources and components and improving the performance of consumer electronic products. The product evenly dissipates heat and also provides thermal isolation in terms of thickness.Graphite flake can be divided into natural graphite flake and artificial graphite flake.
1. Fast heat conduction in the horizontal direction, higher than copper and aluminum
2. Low thermal resistance, 40% lower than aluminum and 20% lower than copper.
3. Soft, ultra-thin, up to 0.025mm, easy to install.
4. Light weight, 25% lighter than aluminum and 75% lighter than copper.
5. Easy to cut, and can be cut into any size according to customer's needs.
6. It can be covered with plastic film for insulation and convenient operation.
7. Can be coated with copper foil, aluminum foil and other materials.
