The rapid development of new energy vehicles has raised higher demands for the protection of core electronic components. Organosilicon-based electronic encapsulants, as an important protective material, are widely used in this field.
These products are primarily used to encapsulate and protect various electronic components within the "three-electric" systems (battery, motor, and electronic control unit) of new energy vehicles. Critical components such as battery management systems, motor controllers, and onboard chargers contain numerous precision electronic parts that generate heat during operation and are exposed to complex operating conditions—including vibration, moisture, and oil contamination—during vehicle travel. Organosilicon encapsulants fully envelop these components, forming an integrated protective barrier. Their excellent resistance to both high and low temperatures (typically maintaining elasticity between -50°C and 200°C) ensures functional reliability even in extreme cold or heat. Their strong electrical insulation safeguards high-voltage systems, while their inherent flexibility effectively absorbs and mitigates mechanical vibration and shock, protecting internal components. In addition, some organosilicon encapsulants also possess thermal conductivity, aiding in the establishment of efficient heat dissipation pathways to maintain stable operation of the electronic systems.
