Description
High thermal conductivity Graphite film is a thermal interface material which is very thin, synthetically made, has high thermal conductivity, and is made from a higly oriented graphene polymer film. It is ideal for providing thermal management/heat-sinking in limited spaces or to provide supplemental heat-sinking in addition to conventional means. This material is flexible and can be cut into customizable shapes.
