Details Images
Adhesive thermal graphite sheet has
Excellent thermal conductivity: up to 1950 W/m•K (2 to 5 times as high as copper, 3 to 8 time as high as aluminum)
High precision measurement standard during processing period
Flexible and easy to be cut. (Withstands repeated bending)
Higher thermal conductivity than copper material
Product Usage
Synthetic graphite sheet
can be applied on Smartphone
Pyrolytic Graphite Sheet (PGS) can deliver the heat, which is generated by the CPU/Flash chip on Cell Phones’ mainboard PCB, evenly to the Cellddle metal steel bracket and framework. Meanwhile the heat from the high heat-making CPU chip can be spread throughout the plane of graphite sheet rapidly. The part hot spots are eliCellnated and the chip can be kept in appropriate temperature range to get the high performance.
Synthetic graphite sheet
can be applied on Computer
The thermal and electrical properties of graphite sheet have very significant anisotropic properties. The diaphragm structure prepared by special process can obtain XY plane up to 1800W/MK thermal conductivity, Z-axis vertical thermal conductivity 20-30W/MK, which is common copper aluminum foil. 4-6 times, for notebooks, tablets and other products that require strict design space, the heat dissipation problem is the core.
