Thermally conductive silicone gaskets belong to a small category in the electronic and electrical industry and belong to insulating materials. The thermal conductive silicone gasket is a thermal conductive medium material synthesized by a special process with silica gel as the base material and various auxiliary materials such as metal oxides added. In the industry, it is also called thermally conductive silicone pad, thermally conductive gasket, thermally conductive silicone pad, and thermally conductive silicone sheet.
The thermal conductive silicone gasket material is a thermal conductive medium, which is used to reduce the contact thermal resistance between the surface of the heat source and the contact surface of the heat sink. It is specially produced for the design scheme of using the gap to transfer heat. It can fill the gap and complete the heating part and the heat dissipation part. It also plays the role of insulation, shock absorption, sealing, etc. It is an excellent thermal conductive filling material used to transfer the surface temperature of the heat source to the heat sink or the air.
Thermally conductive silicone gaskets can be divided into: ordinary thermally conductive silicone sheets, high thermally conductive silicone sheets, low-volatile thermally conductive silicone sheets, thermally conductive silicone sheets with glass fiber, adhesive-backed thermally conductive silicone sheets, and backed silicone cloth thermally conductive silicone sheets.
At present, the thermal conductivity of domestic thermal silica pads can be between 1-10W/m·K. For example, the thermal conductivity of CoolThermo LC1000 is 10.0W, and the thermal conductivity of LC100 is 1.0W.
The thermal conductive silicone gasket also has low oil separation (tends to zero), high and low temperature resistance, water resistance, ozone resistance, and weathering resistance. It has the effect of shock absorption and sound absorption, EMC, insulation performance, thermal conductivity range and stability, ease of installation, testing, reusability, bridging of structural process differences, and reducing the process work of radiators and heat dissipation structural parts. Poor requirements, so the application of thermally conductive silicone sheets can also be widely used!
