As the automotive industry evolves, materials must offer durability, safety, and multifunctionality. Silicone oil, with its excellent thermal stability, lubrication, electrical insulation, and weather resistance, plays a key role in both vehicle manufacturing and maintenance.

In automotive electrical systems, silicone oil serves as an insulating lubricant for connectors, helping to prevent arcing and contact failure. Its moisture resistance makes it ideal for sensors, control modules, and terminals operating in humid, high-temperature, or dusty environments.

Silicone oil also protects and lubricates rubber and plastic parts, such as door seals, sunroof tracks, engine hinges, and brake system O-rings. It does not corrode or degrade materials, retains flexibility at low temperatures, and extends part life by slowing aging.

In vehicle interiors, silicone oil is used to reduce noise and friction in dashboard panels, buttons, and door components. Low-viscosity grades enhance plastic surface gloss, giving interiors a clean and refined appearance while repelling dust.

Some modified silicone oils are used as high-temperature lubricants or sealing agents in engine and transmission systems. Their high flash points and low volatility ensure performance under extreme heat and pressure.

Silicone oil is also found in glass anti-fog treatments, water-repellent coatings, and polishes, improving safety and aesthetics.

In electric vehicles, silicone oil supports critical functions such as battery cooling, electrical insulation, and drivetrain sealing, helping ensure system reliability and thermal management.

Overall, silicone oil’s multifunctionality and stability make it a valuable material in modern vehicles, enhancing both performance and user experience.
