With the development of science and technology, electronic components and logic circuits tend to be denser, multi-functional, miniaturized and modular, which puts forward higher requirements for the stability of electrical appliances. In order to prevent moisture, dust and harmful gases from invading electronic components, slow down vibration, prevent external force damage, stabilize component parameters, and minimize external adverse effects, electronic components need to be potted. The improvement of electrical power requires potting materials to have good thermal conductivity and insulation properties at the same time. Because if the heat cannot be conducted in time, it is easy to form a local high temperature, which may damage the components and components, thereby affecting the reliability and normal working cycle of the system. Silicone rubber has become the first choice for potting due to its excellent physical and chemical properties and process properties. Adding high thermal conductivity fillers can obtain thermally conductive and insulating electronic potting silicone rubber. With the continuous maturity of the technology, high thermal conductivity electronic potting silicone rubber will play an increasingly important role in the application of electronic appliances.
