20000S/Cm 1900W/M.K Thermal Conductive Graphite Sheet
Manufacturer Custom High Conductive Thermal Graphite Sheet Used In Phone Cooling
Synthetic graphite is a material consisting of graphitic carbon which has been obtained by graphitizing of non-graphitic carbon, by CVD from hydrocarbons at temperatures above 2500 K, by decomposition of thermally unstable carbides or by crystallizing from metal melts supersaturated with carbon.
Key properties
1.Excellent thermal conductivity:600 to 1900 W/m.k
(2 to 4 times as high as copper,3 to 6 time as high as aluminum)
2.Light weight: Specific gravity:0.85 to 2.17 g/cm3
(1/4 to 1/10 of copper,1/1.3 to 1/3 of aluminum in density)
3.Flexible and easy to be cut or trimmed(withstands repeated bending)
Applications
1.Cellular phone,DVC,DSC,PC and peripherals,pickup
2.Semiconductor manufacturing equipment
(Sputtering,Dry etching,Steppers)
3.Optical communications equipment
The graphite sheet is widely used in LED line.
