Thermal graphene film with PET
-High thermal conductivity
-Thin graphene sheet
-ROHS & UL listed
-Industry direct price

The 0.025mm thermal graphene film is a thermal interface material which is very thin, synthetically made, has high thermal conductivity, and is made from a higly oriented graphene 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
