Thermal conductivity of graphite is a new kind of heat conduction and heat radiation material, along the two party uniform heat conduction, shielding heat sources and components indeed improved consumer electronic products.Color is generally black,is made of natural graphite through the fine processing, heat conduction coefficient in the horizontal direction is up to 1500W/M-K. The use of IC, CPU, MOS, LED, fins, LCD-TV, notebookcomputer, communication equipment, wireless switches, DVD, handheld devices, etc..
