Silicone grease-HongYe silicone

Silicone grease      Silicone grease is methyl silicone oil and fumed silica by mechanical mixing and some physicochemical process and made of translucent resin material, tasteless, odorless, non-toxic, non-corrosive, has excellent electrical insulation properties, high and low temperature resistance, oxidation resistance, chemical stability and lubricating property. High flash point, low vapor pressure, freezing point, in the -50 ~ 180 ℃temperature range for long-term use. The product has good water repellency, rust-proof, various instruments, such as earthquake damping can also be used as a mold release agent and defoaming agent.      Silicone grease is common standards are: penetration, volatile, oil from the degree, dielectric constant, dielectric loss tangent, volume resistivity, dielectric strength.      Introduction of a heat conductive silicone grease, silicone grease is used to fill the gap between the CPU and the heat sink material a, this material is also known as thermal interface materials. Its role is used to heat sink conduction CPU emitted heat, so that the CPU temperature is kept at a stable working level, prevent CPU because of bad heat damaged, and prolongs the service life.      The heat dissipation and heat application, even the surface is very smooth two surface in contact with each other when there will be a gap appeared, these voids in the air is a poor conductor of heat, will hinder the heat to the heat sink conduction. The heat conductive silicone grease is a kind of can fill those gaps, so that the heat conduction is more smooth and rapid material.      Heat conductive silicone grease is a thermally conductive and electrically insulating silicone material, almost never cured, in -50℃ to +230℃temperature to maintain long-term use of liquid state. Not only has excellent electrical insulation, and has excellent thermal conductivity, and has low oil separation degrees (tending to zero ), high and low temperature resistance, water resistance, ozone, weathering aging,. It can be widely applied to various kinds of electronic products, electrical equipment in the body of the heat ( power tubes, silicon controlled electric heating reactor, etc.) and cooling facilities ( heat sink, heat, shell etc.) between the contacting surfaces, as the heat transfer medium action and moisture-proof, dust-proof, anti-corrosion, such as earthquake resistance. Suitable for the microwave communication, microwave transmission equipment, special purpose microwave power, power supply and other various microwave devices surface coating or encapsulating, the silicon material on the heat generating electronic component, provides excellent heat conduction effect. Such as: transistors, CPU assembly, thermistor, temperature sensor, automotive electronics, car refrigerator, power module, the printer head.      Now there are many types of grease, different parameters and physical characteristics determine the different uses. For example, some suitable for CPU thermal conductivity, some memory applies heat, some applicable to power thermal conductivity ... ...
