Phenyl silicone oil lubricant has excellent sealing performance, which is mainly due to its special molecular structure and physical and chemical properties. The following are the main advantages of phenyl silicone oil in sealing performance:

1. Low volatility and high flash point
Phenyl silicone oil has low volatility and high flash point, can remain stable in high temperature environment, is not easy to volatilize or burn, thereby reducing the risk of sealing failure caused by volatilization.

2. Good lubricity and sealing
The molecular structure of phenyl silicone oil enables it to form a uniform lubricating film on the contact surface, reducing friction and wear, while effectively filling the sealing gap to prevent medium leakage.
Its lubricity can reduce the movement resistance of the seal and extend the service life of the seal.

3. Excellent high and low temperature resistance
Phenyl silicone oil maintains stable physical and chemical properties in a wide temperature range (-70℃ to above 250℃), and will not harden or thin due to temperature changes, ensuring the reliability of sealing performance.

4. Chemical inertness and media resistance
Phenyl silicone oil has excellent tolerance to most chemical media (such as acids, alkalis, solvents, etc.), is not prone to chemical reactions or swelling, and is suitable for use in complex media environments.

5. Good compatibility
Phenyl silicone oil has good compatibility with sealing materials such as rubber, plastic, and metal, and will not cause corrosion or swelling to seals, ensuring the long-term stability of the sealing system.

6. Radiation resistance
Phenyl silicone oil has excellent radiation resistance and is suitable for use in radiation environments such as nuclear power plants and aerospace to maintain the stability of sealing performance.

7. Low surface tension
The low surface tension of phenyl silicone oil enables it to spread quickly and fill tiny gaps to form an effective sealing layer to prevent gas or liquid leakage.

8. Electrical insulation performance
Phenyl silicone oil has good electrical insulation performance and is suitable for use as a sealing and lubricating medium in electrical equipment to prevent electrical breakdown and short circuit.
