Thermal conductive silicone
Thermal conductive silica gel, also known as thermal paste, heat dissipation paste, is a kind of high thermal conductive insulating silicone material, unlike thermal silicone grease almost never solidified, can be in -50β - +250β temperature for a long time to maintain the use of grease state. It has excellent electrical insulation, excellent thermal conductivity, low oil separation (tends to zero), high and low temperature resistance, water resistance, ozone resistance, climate aging resistance. Its characteristics are non-toxic, tasteless and non-corrosive, in line with ROHS standards and related environmental requirements, stable chemical and physical properties.
Main function: used to fill the gap between heating element and cooling device, increase their contact area, so as to achieve the thermal conductivity effect, so that the heat of electronic components when working effectively out of the transmission.
Widely applied to all kinds of electronic products, electrical equipment in the heating body (power tube, silicon controlled, electric heating reactor, etc.) and heat dissipation facilities (radiator, radiator, shell, etc.) between the contact surface, heat transfer medium, can improve the effect of heat dissipation.
