Silicone oil is used as shock absorption and damping oil
Silicone oil is widely used as a shock-absorbing and damping medium in the mechanical manufacturing and instrumentation industries due to its unique viscosity-temperature characteristics, wide viscosity range, excellent thermal stability, and high compressibility.

Improvement of engine durability:
In the torsional vibration absorption damper of diesel engines, the use of high-viscosity (25°C tens of thousands to hundreds of thousands of mm²/s) dimethyl silicone oil can effectively enhance the durability and stability of the engine.

Automotive engine cooling system:
As a damping oil for automotive engine cooling fans, dimethyl silicone oil helps improve the efficiency and reliability of the cooling system.

Clutch oil for four-wheel drive vehicles:
In four-wheel drive (4WD) vehicles, using dimethyl silicone oil with a viscosity of 10 Pa·s as clutch oil can optimize the switching operation of the drive mechanism, especially during sharp turns or driving on rough roads (such as snow or mud), improving the controllability and performance of the vehicle.

Selection of shockproof oil:
According to different vibration force requirements, choose the appropriate viscosity of dimethyl silicone oil as the shockproof oil for automobile and aircraft instruments to ensure accurate signal output and stable pointer readings.

Damping of sensors and instruments:
As a damping shock absorber oil for inductive magnetic direction sensors, dimethyl silicone oil can stabilize the output signal and improve the accuracy of the sensor. In addition, as a damping fluid in pneumatic unit combination instruments and as a filling oil in similar instruments, dimethyl silicone oil ensures the stability and reliability of instrument parameters.

Liquid floated gyroscope and accelerometer:
In the automatic flight control system, liquid-floated gyroscopes and float-type accelerometers are used due to their high sensitivity, accuracy, and stability. These instruments use liquid suspension technology to reduce bearing loads and friction torque. The requirements for gyroscopic floating liquids include high density, suitable viscosity, low sensitivity to temperature changes, non-corrosiveness to various materials, high boiling point and high flash point, and good insulation properties. Currently, fully-floating gyroscopes commonly use fluorine-containing organic compounds, while semi-floating gyroscopes mostly use dimethyl silicone oil to meet these strict performance requirements.
