Phenyl silicone oil performs well in low-temperature lubrication, which is mainly due to its special chemical structure and properties. The following is a detailed analysis of the performance of phenyl silicone oil in low-temperature lubrication:

1. Significant low-temperature resistance
Low-temperature resistance of low-phenyl silicone oil: Silicone oil with low phenyl content (phenyl content 5%~10%) is particularly suitable for occasions with high cold resistance requirements. Even at extremely low temperatures of -70°C, low-phenyl silicone oil can still maintain fluidity, providing reliable lubrication for equipment that needs to work in cold environments.
Fluidity advantage: Due to its stability at low temperatures, phenyl silicone oil can still maintain good fluidity at extremely low temperatures, which is difficult for other oils to achieve.
2. Excellent lubrication performance
Lubrication effect: Phenyl silicone oil has excellent lubrication performance, which can effectively reduce friction and wear and extend the service life of equipment.
Wide application: In the field of electronic and electrical equipment, phenyl silicone oil is widely used as a high and low temperature lubricant. In addition, when carbon black, potassium soap or platinum disulfide are added, they can be made into high-temperature grease for lubrication of high-temperature fan bearings, ball bearings, automobile engines, textile dryers and other equipment.
3. Comprehensive performance advantages
High viscosity-temperature coefficient: Compared with dimethyl silicone oil, phenyl silicone oil has a higher viscosity-temperature coefficient, which means that when the temperature changes, its viscosity changes relatively little, thus maintaining stable lubrication performance.
Strong anti-compression performance: Under pressure, the anti-compression performance and viscosity of phenyl silicone oil change faster, and it can adapt to more complex working conditions.
IV. Practical application cases
Application in hydraulics, instruments, electrical insulation, etc.: Phenyl silicone oil is not only used for low-temperature lubrication, but also widely used in hydraulics, instruments, electrical insulation, etc. For example, phenyl vinyl silicone oil and phenyl hydrogen silicone oil can be used to prepare high-temperature and radiation-resistant addition silicone rubber to improve the high-temperature and radiation resistance of rubber.
Application in extreme temperature environments: In the fields of aerospace, automobile manufacturing, electronic equipment, etc., higher requirements are placed on the high and low temperature resistance of silicone oil. Phenyl silicone oil plays an important role in these fields with its excellent low-temperature resistance and lubrication performance.
In summary, phenyl silicone oil performs well in low-temperature lubrication, with significant low-temperature resistance, excellent lubrication performance and comprehensive performance advantages. Therefore, phenyl silicone oil is an ideal choice in situations where low-temperature lubrication is required.
