With the ever-changing development of electronic products, silicone potting compound is more and more widely used in electronic products. Silicone potting compound is a kind of liquid glue injected in the electronic component parts, can provide excellent heat dissipation ability and flame retardant performance for electronic components, but also can effectively improve the shock resistance of electronic components, moisture resistance, to ensure the stability of the use of electronic components. The performance of silicone potting compound is very important for electronic products, so what are the important indicators to measure the performance of silicone potting compound?
Thermal conductivity:
As the power of electronic products continue to improve, many electronic components in the use of the process will produce a large amount of heat, if this heat dissipation is not timely, it is easy to cause high-temperature overheating of electronic components, resulting in malfunction, thus affecting the service life of electronic and electrical products. Thermal conductivity is to measure the material thermal conductivity and heat dissipation of an important indicator, the higher the thermal conductivity, thermal conductivity and heat dissipation effect is the better, the components can produce heat quickly dissipate lead out, thereby extending the service life of electronic products, so high thermal conductivity silicone potting compound is more popular in the market.
Electrical Properties:
Dielectric strength is a measure of the electrical strength of a material when used as an insulator. The greater the dielectric strength of a material, the better its quality as an insulator. Volume resistivity is the impedance of a material to electric current per unit volume and is used to characterize the electrical properties of a material. Usually the higher the volume resistivity, the higher the efficiency of the material used as electrical insulation components. Silicone potting compound electrical insulation, potting in electronic products, can effectively improve the insulation between the internal components and lines of electronic products.
Mechanical properties:
Silicone potting adhesive mechanical strength which is an important indicator of tensile strength, that is, on behalf of the toughness of the silicone potting adhesive, silicone potting adhesive in the potting product curing, the gel if too brittle to resist the outside world of vibration and external forces is very weak, easily lead to the gel rupture shells, which affects the protective properties, so the mechanical strength of the silicone potting adhesive is very important.
