FAQS on graphite thermal sheet

Q: What is the thermal conductivity of a graphite sheet?

A: Graphite sheets typically have a thermal conductivity ranging from 300 to 1,900 W/mK, depending on their purity and structure. This makes them highly effective for heat dissipation in electronics and industrial applications.

Q: How does a graphite thermal sheet improve device performance?

A: A graphite thermal sheet efficiently transfers heat away from sensitive components, reducing overheating risks. Its lightweight and flexible design allows seamless integration into compact devices like smartphones and laptops.

Q: What distinguishes thermal pyrolytic graphite from standard graphite sheets?

A: Thermal pyrolytic graphite (TPG) is manufactured through high-temperature decomposition, achieving superior in-plane thermal conductivity (up to 1,900 W/mK). Standard graphite sheets offer lower conductivity and are less specialized for extreme thermal management.

Q: Are graphite thermal sheets electrically conductive?

A: While graphite sheets conduct heat exceptionally well, they are also electrically conductive. Insulating layers or coatings are often added for use in electronic circuits to prevent shorting.

Q: Where are graphite thermal sheets commonly applied?

A: These sheets are widely used in electronics (e.g., CPUs, LEDs), automotive systems, and aerospace components. Their high thermal efficiency and thin profile make them ideal for space-constrained environments.
