Thermal graphite insulation film for LCD
Description
Thermal graphite insulation film for LCD is a thermal interface material which is very thin, synthetically made, has high thermal conductivity, and is made from a higly oriented graphite polymer film. It is ideal for providing thermal management/heat-sinking in limited spaces or to provide supplemental heat-sinking in addition to conventional means. This material is flexible and can be cut into customizable shapes.
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
