Graphite film is a kind of graphite film, because carbon element is a non-metal element, but it has the electrical and thermal conductivity of metal materials, and also has the same plasticity as organic plastics, and also has special thermal properties, chemical stability, lubrication and coating. It has some good process properties, such as those applied on solid surfaces. Therefore, thermally conductive graphite has been widely used in many fields such as electronics, communications, lighting, aerospace, national defense and military industry. Graphite film is mainly used for internal shock absorption and heat dissipation of electronic products.
High thermal conductivity graphite film is a new type of heat dissipation material developed in recent years using the excellent thermal conductivity of graphite. This product is a sheet material with extremely high thermal conductivity through repeated heat treatment of a carbon-based polymer film under special sintering conditions. Graphite film has a unique crystal grain orientation, conducts heat uniformly in two directions, and the laminar structure can be well adapted to any surface, shielding heat sources and components while improving the performance of consumer electronics. Widely used in: notebook computers, smart phones, LED lights and wearable devices, etc.
As the smartphone market will maintain a growth rate of more than 10% in the future, the demand for high thermal conductivity graphite film is very high. Especially under new trends such as Win10 and super large screens, the shipment of tablet PCs has also further increased. Wearable devices are also developing rapidly.
The major global players in this industry are: Panasonic of Japan, Graftech of the United States, Kaneka of Japan and China's CZTY Carbon Technology Group.
