Fluorosilicone oil exhibits excellent long-term stability in automotive sensor sealing, with its core advantages lying in its outstanding high-temperature resistance, oil resistance, and chemical stability, effectively coping with the harsh conditions in the sensor's operating environment.

1. High-Temperature Resistance
Fluorosilicone oil can operate stably in a temperature range of -40℃ to 200℃. Even under prolonged high-temperature conditions, its molecular structure changes slowly, effectively delaying aging and maintaining sealing performance.
2. Oil Resistance and Chemical Stability
Fluorosilicone oil has strong resistance to media such as engine oil and fuel, effectively preventing media erosion and avoiding degradation of sealing performance. Its high chemical stability means it does not easily react with chemical substances inside the sensor, ensuring long-term sealing reliability.
3. Application Scenarios
Fluorosilicone oil is widely used in automotive sensor sealing, such as engine crankshaft front and rear oil seals, gearbox oil seals, and fuel system seals. These parts require extremely high resistance to high temperatures and oil.
4. Service Life
Under ideal operating conditions, the service life of fluorosilicone oil seals can reach 8-10 years. Even in harsh environments, it can maintain stable performance for 3-5 years.
5. Technical Advantages
Fluorosilicone oil forms a hydrophobic and inert protective layer through surface film-forming technology, isolating moisture, oxygen, and corrosive media, reducing photo-oxidative aging, and further ensuring the long-term stability of the sealing system.
