Thermal conductive silica grease and thermal conductive silica gel

        Heat conductive silica gel is a kind of potting adhesive which can be solidified at room temperature. The biggest difference between heat conductive silica gel and heat conductive silicone grease is that heat conductive silica gel can be solidified and has certain bonding performance.

       Heat conducting silica gel is generally used on the surface of some electronic parts and chips with small heat output. The thermal conductive silica gel sheet has very good thermal conductivity and filling property. Its own softness can fill the gap between the heating element and the heat dissipation module, the metal mechanism and the shell, quickly dissipate the heat energy, improve the working efficiency of the element, and achieve the purpose of prolonging the service life of the equipment.

      Thermal silicone grease is a kind of material used to fill the gap between CPU and heat sink. Its function is to transmit heat from CPU to heat sink, keep CPU temperature at a stable working level, prevent CPU from damage due to poor heat dissipation, and extend service life.

      In the application of heat dissipation and heat conduction, even the two surfaces with very smooth surface will have gaps when contacting each other. The air in these gaps is a bad conductor of heat, which will hinder the heat conduction to the heat sink. Thermal conductive silicone grease is a kind of material that can fill these gaps and make the heat conduction more smooth and rapid.

      Now there are many types of silicone grease on the market. Different parameters and physical properties determine different uses. Some are suitable for heat conduction of CPU, some are suitable for heat conduction of memory, some are suitable for heat conduction of power supply, some are electronic products, heat dissipation of power supply, fast temperature measurement of sensor, etc. The working temperature of thermal conductive silicone grease is generally not more than 200 ℃, the high temperature can reach 300 ℃, and the low temperature is generally about - 60 ℃.

       Thermal conductive silicone grease is a kind of high thermal conductive and insulating silicone material, which is almost never solidified. It can be used in the temperature of - 50 ℃ - + 230 ℃ for a long time. It not only has excellent electrical insulation, but also has excellent thermal conductivity. At the same time, it has low oil separation (tends to zero), high and low temperature resistance, water resistance, ozone resistance and weather aging resistance. It can be widely applied to the contact surface between the heating body (power tube, thyristor, electric heating reactor, etc.) and the heat dissipation facilities (heat sink, heat strip, shell, etc.) in various electronic products and electrical equipment, playing the role of heat transfer medium and the performance of moisture-proof, dust-proof, corrosion-proof and shock proof. It is suitable for surface coating or overall sealing of various microwave devices such as microwave communication, microwave transmission equipment, microwave special power supply, stabilized voltage power supply, etc. this kind of silicon material provides excellent heat conduction effect for the electronic components generating heat. For example: transistor, CPU assembly, thermistor, temperature sensor, automobile electronic parts, automobile refrigerator, power module, printer head, etc.
