Graphite sheet
Synthetic graphite sheet, also known as artificial graphite sheet, is a new type of thermal interface material made of polyimide.
It adopts advanced carbonization, graphitization and calendering process to produce a thermally conductive film with unique lattice orientation through high-temperature sintering at 3000 °C.
With the upgrading of electronic products, the growing number of mini, highly integrated and high-performance electronic devices, resulting in a large number of heat dissipation management needs. DSN can provide thinnest graphite foil 12um with thermal conductivity up to 1900W/ m-K.

graphite sheet

Today more and more high-tech electronics are used such as the latest smartphones in your pocket, the thin, Ultra-thin laptops on your desk, and the ultra-high definition television on your wall. As electronics get faster, thinner and more powerful, the thermal challenges are more demanding than ever. The heat source is distributed in the charging module, six-cell aluminum battery, keyboard, PCB, PCU, LCD substrate board, side frame, and receiving signal terminals.

The thermal and electrical properties of graphite materials have a very significant heterogeneity. Through special preparation, the sheet structure can achieve thermal conductivity up to 1800W/MK in the XY plane, and the vertical thermal conductivity to 20-30W/MK on Z-axis, which is 4-6 times as much as common copper aluminum foil. For products with demanding design space, heat dissipation is the core issue.

Thin and light graphite sheet has the ability to effectively spread heat and is an ideal choice for cost effective thermal management. 

Smartphones cooling
Today's smart phones face unique challenge of heat treatment. The thermal processor they contain must be cooled, the shell of phones has strict touch temperature limitation, and the display must be protected from hot spots and thermal gradients. All these must be solved by thin and efficient heat-transfer products. With the largest range of graphite sheet application, the thermal solutions can be solved to meet the high performance demands of the industry.
Tablets and Ultrabooks
The demand for high-performance heat spreaders becomes more urgent as the tablets and Ultrabooks become thinner and lighter. The thermal processor needs cooling, and the shell’s hot spot must be eliminated. All these must be done by thin and efficient heat-transfer products. With the widest range of ultra-high performance pyrolytic graphite sheets, we have the right thermal solutions to meet the performance needs of the industry.
4K/8K Ultra HD
For LED/ LED display, uneven heating is a main cause of color aberration and blurred pictures. And these bad pictures may be seen everywhere on the display or even in the corners. For OLED displays, the non-uniform heat can cause uneven aging of the display, resulting in a noticeable color distortion. High performance graphite sheets can prevent these problems and achieve high quality pictures.
Automotive Batteries Cooling
The battery module must be safe, lightweight and compact for battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs). Using traditional aluminum for heat dissipation will make the battery become thick and heavy. While graphite film directly replaces aluminum and the graphite film can cool the cells during normal charge/discharge operation and to prevent propagation in the event of a cell failure.
