Extremely thermally conductive self-adhesive graphite sheets for spreading heat and cooling electronics. Commonly used in smartphones and tablets, but we have also supplied these to companies in aerospace, automotive, medical devices, and industrial automation.

These pyrolytic graphite sheets have incredible thermal conductivity: 1600W/mK — 4 times that of copper or silver and almost 8 times that of aluminum. It is the most thermally conductive sheet material you can buy today.
We've previously recommended Panasonic's PGS graphite sheets, which were ~$33 for a 180×115mm sheet. Now, we've managed to source these sheets directly from a manufacturer in China. They have the exact same thermal conductivity compared to the Panasonic counterpart of the same thickness, but these sheets are 4.4 times the area. So, you get similar performance at 1/4 the price per unit area. And because of the large 300×300mm size, you get a contiguous area instead of separate pieces, for even better heat spread.
