Electronic potting silicone foam potting

Silicone foam potting compound is also called silicone foam potting glue, which is used for the sealing and bonding of electrical machinery, which can strengthen the overall performance of electronic components, improve the resistance of electronic components to vibration, avoid direct exposure of electrical products to the air, and play the role of dust prevention and moisture prevention. 

DEFINITION OF SILICONE FOAM

Silicone resin is a kind of highly active adsorption material, which belongs to amorphous substance. The main component of silicone resin is silicon dioxide, which is chemically stable and non combustible.

ADVANTAGES OF POTTING SILICONE FOAM

The silicone potting polymer has stable physical and chemical properties, good high and low temperature resistance, and can work at - 40~200 ℃ for a long time. Excellent weather resistance, it can still play a good role in protecting the outdoor environment for more than 20 years, and it is not easy to turn yellow. It has excellent electrical performance and insulation capacity. After potting, it can effectively improve the insulation between internal electrical machinery and lines, and improve the service stability of the power cabinet.

DISADVANTAGES SILICONE FOAM POTTING MATERIAL

Compared with polyurethane polymer and epoxy polymer, the bonding performance of silicone resin is slightly poor. The mechanical properties of silicone resin, such as tensile strength and shear strength, are poor, and the silicone resin has poor oil resistance and solvent resistance.

SCOPE OF APPLICATION ELECTRONIC POTTING SILICONE FOAM

electric cabinet, ring network electric cabinet, power grid, suitable for LED, display screen, photovoltaic materials, diodes, semiconductor devices, relays, sensors, automobile stabilizer HIV, on-board computer ECU, etc., mainly for insulation, moisture-proof, dust-proof and shock absorption.
