What are Graphite sheets?
Graphite sheets are a type of thermal management product used as heat spreaders to improve the thermal transfer between the heat-generating component and a heat sink. They are typically made from natural or synthetic graphite and have a high thermal conductivity, typically in the range of 100 to 350 W/m-K, which is much higher than other common thermal interface materials such as aluminium or copper. Our T68 synthetic graphite sheet boasts conductivity of 1500 W/m-K in the x-y axes.
Graphite sheets can be used in a variety of electronic and industrial applications, including electronic devices, power semiconductors, LED lighting, and telecommunications equipment. They can be used as a replacement for thermal grease or thermal paste to improve the thermal conductivity between the heat source and the heat sink.
One of the main advantages of graphite sheets is that they can handle high temperatures and thermal cycling, this makes them suitable for use in high-power applications where traditional thermal interface materials may not perform as well. Additionally, they are also highly flexible and conformable, which means that they can be applied to uneven surfaces to fill small gaps between the heat source and the heat sink.
Graphite sheets can be used in conjunction with PET liners to provide electrical insulation properties, which makes them suitable for use with electronic devices and power semiconductors. Graphite sheets have a long shelf life; this is because they don’t dry out or lose their effectiveness over time.
It’s worth noting that graphite sheets can be more difficult to apply than other types of thermal interface materials, such as thermal pads or thermal grease, and can be awkward to remove once applied. Additionally, their effectiveness can depend on the specific application and conditions, so it’s important to carefully select the right product and ensure proper installation.
In summary, graphite sheets are a type of thermal management product used to improve heat transfer between the heat source and heat sink. They are typically made from natural or synthetic graphite and have a high thermal conductivity. This high thermal conductivity allows for efficient heat transfer and dissipation, making them suitable for use in high-power electronic applications where traditional thermal interface materials may not perform well.
