    Characteristic

    Graphite thermal film is a novel material created by compressing expandable graphite with a purity exceeding 99.5%. It possesses a unique crystal grain orientation, allowing for even heat dissipation in two directions. This not only shields electronic components and heat sources, but also improves product performance. The film can be combined with other materials, including metal, plastic, adhesive, aluminum foil, and PET, to meet various design requirements. It features high temperature and radiation resistance, as well as excellent chemical stability. Furthermore, it boasts low thermal resistance (40% lower than aluminum, 20% lower than copper) and is lightweight (30% lighter than aluminum, 75% lighter than copper). Consequently, it is extensively utilized in various electronic products, such as flat panel displays, digital cameras, mobile phones, LEDs, etc.
