More than three times as high as copper and six times as high as aluminum)
Features
“GRAPHINITY™” can spread heat in planar direction and can suppress a heat spot.
Light weight Density about 2 g/cm³, thickness : 25 µm, 40 µm
Flexibility Withstands repeated bending, R = 2 mm, 270°, more than 10000 times bending. Easy to manufacture such as punching and bending.
High electromagnetic shielding e�ect.
Extremely low water absorption.
GRAPHINITY™ dissipates heat spots by di�using heat rapidly over the surface, thanks to high thermal conductivity of 1,500 W/mK in the planar direction.
Comparison of heat spreading ability between three materials of the same thickness
