With the rapid development of electronic products, silicone potting glue is increasingly used in electronic products. Silicone potting glue is a liquid glue poured on electronic components. It can provide excellent heat dissipation and flame retardant properties for electronic components. It can also effectively improve the shock and moisture resistance of electronic components and ensure the stability of electronic components. The performance of silicone potting glue is very important for electronic products. So what are the important indicators for measuring the performance of silicone potting glue? Please see the following explanation.

1. Thermal conductivity Thermal conductivity of silicone potting glue
As the precision of electronic products continues to improve, many electronic components will generate a lot of heat during use. If this heat is not dissipated in time, it is easy to cause the electronic components to overheat and malfunction, thus affecting the service life of electronic and electrical products. Thermal conductivity is an important indicator for measuring the thermal conductivity and heat dissipation of materials. The higher the thermal conductivity, the better the thermal conductivity and heat dissipation effect, which can quickly dissipate the heat generated by the components, thereby extending the service life of electronic products. Therefore, silicone potting glue with high thermal conductivity is more popular in the market.
2. Electrical performance Dielectric strength of silicone potting glue
Dielectric strength is a measure of the electrical strength of a material as an insulator. The greater the dielectric strength of a substance, the better its quality as an insulator. Volume resistivity is the impedance of a material to current per unit volume, which is used to characterize the electrical properties of a material. Generally, the higher the volume resistivity, the higher the efficiency of the material as an electrical insulation component. Silicone potting glue has strong electrical insulation. After being potted in electronic products, it can effectively improve the insulation between internal components and circuits of electronic products.
3. Mechanical properties Mechanical strength of silicone potting glue
One of the important indicators of the mechanical strength of silicone potting glue is tensile strength, which represents the toughness of silicone potting glue. After the silicone potting glue is cured, if the colloid is too brittle and is very weak in resisting external vibration and external force, it is easy to cause the colloid to break and peel off, thus affecting the protectiveness, so the mechanical strength of silicone potting glue is very important.
