Panasonic Graphite Sheet thermal interface material offers a thermal management solution for heat sensitive applications such as LED lighting, helping to improve efficiency and to greatly extend the life of LEDs. Copper is typically used for spreading heat, due to its good conducting property but today’s applications are pushing the limits of this material. As a better alternative, Panasonic Pyrolytic Graphite Sheet has thermal conductivity across its plane from 2 to 5 times that of pure copper.
