Dimethyl silicone oil has a wide range of important applications in the automotive field. With its unique properties, it plays a key role in improving the performance, safety and comfort of automobiles.

In automobile engine systems, dimethyl silicone oil is widely used as a high-quality lubricant. It has excellent high-temperature stability and low-temperature fluidity. When the engine is running at high temperature, it can effectively reduce the friction coefficient between parts, reduce wear and extend the service life of the engine. For example, in the lubrication of high-speed running parts such as the crankshaft and piston of the engine, the stable lubricating film formed by dimethyl silicone oil can withstand high temperatures of up to hundreds of degrees without decomposition, ensuring that the engine can still run smoothly under extreme working conditions. Compared with traditional lubricants, it has less evaporation loss at high temperatures, can maintain good lubrication performance for a long time, and reduce the maintenance frequency and cost of the engine.

In terms of automobile braking systems, dimethyl silicone oil is used as an important component of brake fluid. Brake fluid needs to have good fluidity and stability to ensure that the brake pressure can be transmitted quickly and accurately under different temperature environments. The low freezing point and high boiling point characteristics of dimethyl silicone oil prevent it from freezing in the cold winter and vaporizing and failing due to high temperature in the hot summer. For example, in high-cold areas, the vehicle braking system uses brake fluid containing dimethyl silicone oil, which can work normally at -40℃ or even lower temperatures, providing reliable protection for the safe braking of the vehicle. At the same time, it has good compatibility with rubber seals in the braking system, does not cause the seals to swell or age, and ensures the sealing and reliability of the braking system.

The automotive shock absorption system is also inseparable from dimethyl silicone oil. It is used in shock absorbers to play a damping and buffering role. When the vehicle is driving on a bumpy road, the dimethyl silicone oil in the shock absorber absorbs and dissipates vibration energy through its viscosity, keeps the body stable, reduces the impact of vibration on the driver and passengers, and improves ride comfort. For example, in the shock absorption system of a high-performance sports car, the precise deployment of dimethyl silicone oil can provide appropriate damping force according to different road conditions and driving modes, which not only ensures the stability and controllability of the vehicle when driving at high speed, but also effectively filters vibration when passing through bumpy sections such as speed bumps, bringing excellent driving experience to the driver.

In addition, dimethyl silicone oil is also used in automotive interior materials. It can be used as an additive to treat car seat leather and plastic interior parts, giving these materials good hand feel, wear resistance and stain resistance. Car seat leather treated with dimethyl silicone oil is softer and smoother, less susceptible to dust and stains, and has a certain waterproof performance, which is convenient for daily cleaning and maintenance, and improves the overall quality and aesthetics of the car interior.
