<p>Difference between electronic silicone thermal grease and thermal silicone Adhesive thermal silica and thermal grease are thermal interface materials. Thermal silica: Thermal silica is thermal RTV plastic, at room temperature can be cured of a potting, thermal grease and the biggest difference is that thermal silica can be cured, there is a certain adhesive properties. Thermal film: The industry has a material called thermal film, generally used for some smaller heat of electronic components and chip surface. The thermal conductivity of this material is relatively small, thermal conductivity is generally low. Thermal grease: Thermal grease is a type of material used to fill the gap between the CPU and the heatsink. Its role is used to heat sink CPU thermal conductivity of the silica gel and thermal grease are thermal interface material. </p><p>Thermal silica: Thermal silica is thermal RTV plastic, at room temperature can be cured of a potting, thermal grease and the biggest difference is that thermal silica can be cured, there is a certain adhesive properties.

Thermal grease: Thermal grease is a type of material used to fill the gap between the CPU and the heatsink. Its role is to heat the heat sink CPU conduction, the CPU temperature is maintained at a level that can work stably, to prevent the CPU because of poor thermal damage, and extend the service life. In cooling and thermal applications, even the two surfaces with a very smooth surface will have voids that come in contact with each other.</p><p> The air in these voids is a poor conductor of heat, hindering the conduction of heat to the heat sink. The thermal grease is a kind of can fill these gaps, so that the conduction of heat more smooth and rapid material. Now there are many types of grease on the market, different parameters and physical characteristics determine the different uses. For example, some suitable for CPU thermal conductivity, some suitable for thermal memory, and some suitable for thermal conductivity of the power supply ... ... and some electronic products, power cooling, sensors, such as rapid temperature measurement can be used. </p><p>Not only has excellent electrical insulation, but also has excellent thermal conductivity, at the same time with low oil (to zero), high temperature, water, ozone, weathering and aging. It can be widely applied to a variety of electronic products, electrical equipment in the heating element (power tube, SCR, heaters, etc.) and cooling facilities (heat sink, cooling bar, housing, etc.) between the contact surface, The role of heat transfer media and moisture, dust, corrosion, shock and other properties. It is suitable for surface coating or integral potting of various microwave devices such as microwave communication, microwave transmission equipment, microwave power supply, regulated power supply and the like. Such silicon materials provide excellent thermal conductivity for generating hot electronic components.</p>
