Graphite Sheet Stickers

Graphite Sheet Supplier & Manufacturer Malaysia


GRAPHINITY is a high thermal conductive graphite sheet that has been developed through our high polymer technologies and ultra heat treatment techniques. This material can spread heat from a heat source quickly, and can decrease the temperature of it.


High thermal conductivity (more than three times as high as copper and six times as high as aluminum)

GRAPHINITY can spread heat in planar direction, and can suppress a heat spot.

Light weight : Density about 2g/cm³, thickness : 25μm, 40μm


Flexible (withstands repeated bending, R = 2mm, 180°, more than 10000 times bending)

Easy to manufacture such as punching and bending

Extremely low water absorption

Have you ever feel your smart phone is overheating after talking for some times over the phone?

Have you ever feel your smart phone is heating up while opening many apps or playing games?

The increasing functionality of smart phone and tablet system which need speedy application processors and computation has accumulated higher temperature on these devices.

How to spread the heat on smart phone and tablet?

Do you know there is a gravy and matt thin layer of Graphite Sheet being pasted on middle-plate (stiffener plate) – behind the Display Screen, and another thin layer of Graphite Sheet is pasted on Back-plate behind the battery and PCB?

The functions of these thin layer of Graphite Sheets is for “Thermal Management”.

Simply to say, it is used to spread the heat which generated from touch-screen, battery and PCB components to ensure the components work in a sustainable temperature.

Compare to the traditional cooling schemes, this new advance cooling solution have high thermal efficiency, it eliminate the “hot spots”, heat source and components shielding.

Main Application ?

  1. Lap-top
  2. High-power LED lighting
  3. Flat panel dispay
  4. Digital Cameras & Handy cam
  5. Smart phone & tablets

Kaneka ranked in Top 5 supplier of Graphite Sheets in worldwide, we are collaborating with the worldwide famous multinational telecommunication companies in supplying our thermal management – Graphite Sheets & Graphite Stickers for the smart phones and tablets.
