Information
Graphite heat sink (film), a new type of thermal conductive heat sink material, chemically composed mainly of a single carbon (C) element, is a Natural Element Minerals. Graphite has a unique grain orientation, conducts heat uniformly in both directions, and the sheet structure adapts well to any surface; thermal conductive graphite sheets ( (Film) In-plane thermal conductivity 1200~1600W/mk, 5~7 times that of aluminum, 3~4 times that of copper. 25% lighter than aluminum and 75% lighter than copper. Graphite heat dissipation film has high application value in eliminating local hot spots, smoothing temperature gradient and changing the direction of heat flow, etc., which belongs to the product heat dissipation. The important application material in the solution.
Graphite heat dissipation film is a polymer film in high temperature, inert atmosphere using advanced synthesis technology, the system made a high degree of crystallinity, lattice orientation, and the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation, the lattice orientation Good thermal conductive film material. Because carbon is a non-metallic element, but has the electrical and thermal conductivity of metal materials, as well as the plasticity of organic plastics. In addition, there are special thermal properties, chemical stability, lubrication and can be applied to solid surfaces and other good process performance, so Thermal conductive graphite sheet (film) is widely used in PDP, LCDTV, NotebookPC, UMPC, and other applications. FlatPanelDisplay, MPU, Projector, PowerSupply. In the heat conduction and dissipation solutions for LED and other electronic products, the natural and artificial graphite heat sinks have excellent performance and are widely available. Our natural graphite heat sink and artificial graphite thermal conductivity film have excellent performance and are widely available. The films can be single or double-sided coated according to the end-user's requirements.
