| 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 about2g/cm3, thickness : 25µm, 40µm |
|
Flexible (withstands repeated bending, R = 2mm, 180°, more than 10000 times bending)
→ Easy to manufacture such as punching and bending. |
|
High electromagnetic shielding effect |
|
Extremely low water absorption |
