Thermal conductivity is an important indicator of the thermal conductivity of the material, high thermal conductivity silicone sheet of thermal conductivity is generally between 1 ~ 10W/m-K, can effectively conduct the heat generated by the electronic equipment to ensure the normal operation of the equipment.
Breakdown voltage is the maximum voltage that thermally conductive silicone film can withstand, the higher the breakdown voltage, the better the insulation of the product. Thermally conductive silicone sheet insulation is good, 1mm thickness electrical insulation index of 4000 volts or more.
Hardness is also a factor to consider when choosing thermally conductive silicone sheet. The harder the product, the worse the contact between the thermally conductive silicone gel and the heat generating parts and heat dissipation parts. The softer the more adequate contact, but not the softer the better, because too soft, not easy to paste.
