Thermal conductive silicone grease, also called thermal paste and thermal conductive paste, is a kind of silicone material with high thermal conductivity and insulation. It can be widely applied to the contact surface between heating elements (power tubes, silicon controlled rectifier, electrothermal reactors, etc.) in various electronic products and electrical equipment and heat dissipation facilities (radiating fins, radiating strips, shells, etc.), and plays a role as a heat transfer medium and has moisture-proof, dust-proof, corrosion-proof and shock-proof properties. It is suitable for surface coating or integral potting of various microwave devices such as microwave communication, microwave transmission equipment, microwave special power supply and regulated power supply.
