Graphite sheet vs copper foil for thermal conductivity

Thermal conductivity comparison

When you look at graphite sheet and copper foil, they are not the same. DASEN graphite sheets have high thermal conductivity. These flexible graphite foil products can reach 1500 to 2000 W/m·K. Copper foil has much lower thermal conductivity, about 400 to 500 W/m·K. So, graphite is three to four times better than copper at moving heat. You can check the table below:

You want the best materials to help your devices stay cool. Flexible graphite foil spreads heat fast and evenly. This helps stop temperature spikes. You can use these materials as heat spreaders in many things. Graphite sheets are a great pick for thermal management.

Heat dissipation performance

It is important to keep your devices cool and safe. Flexible graphite foil acts as a strong heat sink. It moves heat away from hot spots quickly. Graphite sheets can be used as heat spreaders in electronics, batteries, and lights. When you use graphite sheet instead of copper foil, you get better results. Graphite foil can move heat across a big area. This stops parts from getting too hot and keeps your device safe.

Flexible graphite foil also works well as a thermal interface. It fills spaces between chips and heat sinks. This makes your thermal interface materials work better. You can trust graphite to keep your system steady. DASEN graphite sheets do well in real tests. They move heat fast and help your devices last longer.

Tip: You can use flexible graphite foil as a thermal interface in AI servers, smartphones, and LED lights. This helps you get the best heat control.

You want thermal interface materials that are easy to use and work well. Flexible graphite foil gives you both. The properties of graphite sheets make them a smart pick for any heat sink or heat spreader. You can trust these materials for your thermal management needs.

Performance factors

Flexibility and weight

You need materials that fit your devices and keep them cool. DASEN graphite sheets are flexible and light. You can bend them many times and they still work well. Copper foil breaks if you bend it too much. Graphite sheets fit into small spaces in electronics. This gives you more ways to design your devices.

• DASEN graphite sheets can bend a lot and still move heat well.

• Light sheets fit in tight spots and do not make devices heavy.

• Flexible materials help control heat in phones, tablets, and other small devices.
