T68 Synthetic Graphite Sheet
- Ultra high thermal conductivity,electrical conductivity and EMI shielding effect
- Flexible, and bendable
- Ultra thin; Low mass; Environmental
- Low thermal resistance
T68 Synthetic Ultra Thermal Conductive Graphite Sheet is highly oriented pyrolytic graphite sheet with high thermal conductivity. A heat source can reduce temperature by spreading heat over the T68. It is flexible and has features of ultra-thin and high EMI shielding effect.
T68 is a graphite sheet and the thickness of the synthetic graphite sheet made by high-temperature hot pressing can be slightly thicker than other graphite sheets. The XY-axis thermal conductivity is as high as 1500W/m•K. The rapid heat transfer characteristics of the plane can make the heat source expand rapidly to achieve the heat dissipation effect.
Suitable for small size products such as mobile phones, wearable devices, 3C electronic supplies, displays, etc.
The T68 synthetic graphite sheet made by high-temperature hot pressing is widely used in mobile phones, tablets, laptops, and other products that require lightness, thinness, and short length, and uses the advantages of rapid diffusion to achieve passive heat conduction and heat dissipation.
Application：
