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.
Application
Suitable for small size products such as mobile phones, wearable devices, 3C electronic supplies, displays, etc.
Electronic components: Electric Vehicles, 5G, Autopilot System, Mobile Phone, AIOT, HPC (High Performance Computing),Server, IC, CPU, MOS, LED back light, Mother Board, Power Supply,Heat Sink, LCD-TV, Notebook, PC, Telecom Device, Wireless Hub, DDR ll Module, NIC, screens, 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.

TG-P1000 is Graphene and it’s the thinnest and hardest nanomaterial known in the world. It is lower than copper or silver and has the smallest resistivity in the world. Because of its extremely low resistivity and extremely fast electron migration, it is expected to be used to develop a new generation of thinner and faster conductive electronic components or transistors. Since graphene is essentially a transparent and good conductor, it is also suitable for manufacturing transparent touch screens, light panels, and even solar cells.
