Graphite paper is a kind of graphite products made of high carbon and phosphorus flake graphite through chemical treatment and high temperature expansion rolling.
It is the base material for manufacturing various graphite seals. Graphite paper is also called graphite sheet, with the characteristics of high temperature resistance, corrosion resistance, and good electrical conductivity, it can be used in petroleum, chemical, electronics, toxic, flammable, high temperature equipment or parts, can be made into a variety of graphite strip, packing, gasket, composite plate, cylinder pad, etc.
With the acceleration of the upgrade of electronic products and the increasing demand for thermal management of mini, highly integrated and high-performance electronic equipment, a new thermal technology for electronic products has been introduced, namely, a new solution of graphite material thermal solution. This new natural graphite solution makes use of graphite paper with high heat dissipation efficiency, small space, light weight, uniform heat conduction in both directions, eliminates "hot" areas, and improves the performance of consumer electronics while shielding heat sources from the components. The main applications include laptops, flat-panel monitors, digital video cameras, mobile phones and personal assistant devices.
Excellent thermal conductivity: thermal conductivity up to 600-1200 w/(m-k) (equivalent to 2 to 4 times of copper and 3 to 6 times of aluminum), thermal resistance is 40% lower than aluminum and 20% lower than copper
Light specific gravity: 1.0-1.9g /cm3 (the density is equivalent only 1/10 to 1/4 of copper, 1/1.3 to 1/3 of aluminum)
Low thermal resistance, soft and easy to cut (repeated bending)
Ultra-thin: thickness (0.025-0.1mm)
The surface can be combined with metal, plastic, adhesive and other materials to meet different design functions and needs
