HY510 White Thermal Conductive Silicone Grease, this kind of silicone grease is added with high thermal conductivity graphite powder, metal powder and other substances to get better thermal conductivity effect. This product is widely used in filling gaps between CPU and radiator, high power diodes, triodes, silicon controlled elements, heat transfer in the crack in contact with substrate. Also ideal for: Power Transistors, Power LEDs etc. With the help of the high thermal conductivity of graphite, graphite thermo-conductive silicone grease can fill the gap between the device and the heat sink, increase the contact area between them, and get a good heat dissipation effect.
