Synthetic graphite sheet, also known as artificial graphite sheet, is a brand-new heat dissipation material. Using advanced carbonization and graphitization technology, thermal conductive films with unique lattice orientation are fabricated by high-temperature sintering at 3000 ℃. It mainly dissipates heat evenly along two directions, and the lamellar structure can well adapt to any surface.

    Synthetic graphite thermal conductive materials are mainly used in electronic products, so that smart phones, tablet computers, laptops and other product fields have been expanded, the development of synthetic graphite thermal conductive materials is closely related to the downstream industry, the material is very soft, can provide coils, convenient die-cutting processing.

    Synthetic graphite is made of organic polyester film as raw material and sintered at high temperature. It has significant advantages such as high crystallinity and good lattice orientation. The thermal conductivity of the product is extremely high, and the thermal conductivity in the horizontal plane can reach up to 1800W/mK, which is much higher than the thermal conductivity of metal aluminum, copper, and natural graphite.

    Preparation of synthetic graphite sheets

    Through high temperature thermal expansion, graphite carbon atoms are made into synthetic graphite heat sinks, and the synthetic graphite is made into a sheet of stickers by using the favorable characteristics of synthetic graphite, excellent heat conduction and thinness, so that it is attached to the heat source so that it can well disperse a little heat evenly, so that the high heat of a single electronic product can be spread out in a large range, which can well protect the service life of electronic products. It can not only block the contact between the originals, but also play a certain role in earthquake resistance.

    Applications of synthetic graphite

    (1) Thermal conductive heat sink: synthetic graphite can be processed and pressed into synthetic graphite sheet by precision instruments, which is a new thermal conductive heat dissipation material, using advanced carbonization and graphitization technology, through 3000 °C high temperature sintering to produce a thermal conductive film with a unique lattice orientation; At the same time, improve the performance of consumer electronic products, the product uniformly dissipates heat while also providing thermal isolation sheet layered structure in terms of thickness can be well adapted to any surface, the temperature application range is -40~400 °C inert environment, with thermal conductivity in the range of 150-1500W/m-K.

    (2) Electromagnetic shielding materials: synthetic graphite has good thermal conductivity and can realize rapid heat transfer, so it is often used as a thermal conductive device in the heat dissipation system of electronic products. Graphite heat sink is to effectively transfer heat by evenly distributing heat in a two-dimensional plane to ensure that the component works at the temperature it withstands. At the same time, because graphite can conduct electricity, it has a certain function of electromagnetic shielding.

    Synthetic graphite heat dissipation is better than traditional heat dissipation materials such as copper and aluminum under certain application conditions. The heat dissipation capacity needs to be considered as a whole in combination with the specific application environment, including heat absorption capacity, heat conductivity and heat dissipation capacity, etc., and is constrained by many conditions, and needs to achieve a balance to maximize the effect. With the increase of the range of applications, the market demand for synthetic graphite will be more diversified. The graphite heat sink made is not as thin as possible, but should meet the thickness requirements of specific scenes

    Traditional heat dissipation materials are mostly metal, but due to high metal density, high thermal expansion coefficient and low thermal conductivity, it is difficult to meet the requirements of efficient heat dissipation of current electronic products. Synthetic graphite made of heat dissipation film, heat sink by chemical treatment, and then by high temperature expansion and calendering, is the best thermal conductivity material in Franli, so the role of synthetic graphite is very large, widely used in the major electronics industry, used in our lives, if you need synthetic graphite, you can contact us.
