What role does thermal conductive silica gel play in electronic products?

        Thermal conductive silica gel is mostly used in all kinds of electronic products and other products, but it is not widely used in the electronic products industry. Thermal conductive silica gel has excellent weather resistance, corrosion resistance and aging resistance with its high thermal conductivity, excellent thermal conductivity and electrical insulation, wide operating temperature and good stability. Low consistency and good construction performance.


        Thermal conductive silica gel is a kind of silica gel specially used for electronic products. It is used in the contact surface between heating body and heat dissipation facilities in electrical equipment. It has the functions of heat transfer medium, moisture-proof, dust-proof, corrosion-proof and shock-proof. It is also suitable for surface coating or integral encapsulation of various microwave devices, such as microwave communication, microwave transmission equipment, microwave special power supply, voltage regulator power supply, etc. This kind of silicon material provides excellent thermal conductivity effect for heat-generating electronic components.


        Single-component dealcoholic room temperature curable silicone sealant has good bonding property, good bonding property to aluminum, copper, stainless steel and other metals, excellent dielectric property, good heat resistance, generally used in the temperature range of - 50 ~200 C. Alcohols are released during the curing process. They are non-corrosive to polycarbonate (PC), copper and other materials. They fully meet the requirements of EU ROHS directive.


        Typical uses of thermal conductive silica gel are fixed connectors on circuit boards; sealing, fixing and shock-proof of electronic components, such as high-voltage package, mid-cycle, electrical plugs, rectifier tubes and capacitor joint protection; plane bonding and sealing of various mechanical equipment, etc.


        Clean up the surface of the sticky or coated material before use, squeeze the glue onto the cleaned surface after use, and place the sticky or sealed parts in the air for natural solidification. If the amount of silica gel is large, it is not easy to touch the air part, and the curing time will take more time.


        The same silicone gel should be used up as far as possible. If there is no used up silicone gel, it should be sealed and preserved. In the storage process, there may be a small amount of curing phenomenon, which can be used normally without affecting product performance. In a cool and dry environment below 25 for 6 months, products exceeding the shelf life should be confirmed to have no abnormalities before they can be used.
