Phenyl silicone oil performs well in heavy-duty applications. Its unique molecular structure and performance characteristics enable it to maintain excellent lubrication performance and stability under extreme working conditions such as high temperature, high pressure and high load. The following is a specific performance analysis:

1. Excellent thermal stability and high temperature resistance
The thermal stability of phenyl silicone oil is significantly better than that of ordinary silicone oil. The introduction of its phenyl group enhances the rigidity of the molecular chain and reduces the molecular chain breakage and volatilization at high temperature.
Silicone oil with high phenyl content (such as phenyl molar fraction ≥ 45%) can be used for a long time above 250°C, and even after adding stabilizers, it can work stably for hundreds of hours in an environment of 300-350°C.
Application scenarios: Suitable for lubrication of heavy-duty equipment such as high-temperature bearings, gearboxes, hydraulic systems, etc., to reduce lubrication failure and equipment wear caused by high temperature.

2. Excellent lubrication performance and extreme pressure resistance
Phenyl silicone oil has a low friction coefficient and good anti-wear performance. It can form a stable lubricating film under heavy load conditions and reduce direct contact between metal surfaces.
The phenyl group in its molecular structure enhances the strength and adhesion of the lubricating film and improves the load-bearing capacity of the lubricating film under high pressure.
Application scenarios: Suitable for lubrication of transmission parts such as heavy-duty gears, worm gears, chains, etc., to extend the service life of the equipment.

3. Good oxidation resistance and chemical stability
Phenyl silicone oil is not easy to oxidize under high temperature and heavy load conditions, avoiding the sediment and corrosion problems caused by oxidation.
It has good compatibility with metal and non-metallic materials, and will not corrode equipment or affect the performance of sealing materials.
Application scenarios: Suitable for lubrication of heavy-duty equipment such as high-temperature heat treatment equipment and chemical reactors, reducing maintenance costs.

4. Excellent electrical insulation performance
Phenyl silicone oil has a high dielectric constant and low dielectric loss, and performs well in the electrical insulation system of heavy-duty equipment.
Its high flash point and low volatility reduce the risk of fire and explosion and improve the safety of equipment.
Application scenarios: Suitable for insulation and cooling of electrical equipment such as transformers, capacitors, and high-voltage switches.

5. Good low-temperature fluidity and compression resistance
Silicone oil with low phenyl content (such as phenyl molar fraction 5-10%) still maintains good fluidity at low temperatures and is suitable for the startup and operation of heavy-duty equipment in cold environments.
The viscosity of phenyl silicone oil changes little under pressure, which maintains the stability of the lubricating film and reduces energy loss under heavy-duty conditions.
Application scenarios: Suitable for lubrication of heavy vehicles, construction machinery, etc. at extreme temperatures.

6. Environmental protection and biocompatibility
Phenyl silicone oil is non-toxic, odorless, non-corrosive, harmless to the environment and human body, and meets the environmental protection requirements of heavy-duty equipment.
Its biocompatibility also makes it potential for application in medical equipment and food processing equipment.
Application examples
Aerospace field: used for lubrication of heavy-duty equipment such as aircraft engines and hydraulic systems to ensure reliable operation under extreme working conditions.
Automotive industry: used for lubrication of gearboxes and bearings of heavy-duty trucks and construction machinery to improve equipment durability.
Energy industry: used for lubrication of equipment such as wind turbines and nuclear power plants to reduce maintenance costs and downtime.
Notes
Choose the right phenyl content: Choose the right phenyl silicone oil according to the application temperature and load conditions to ensure optimal performance.
Regular inspection and maintenance: Although phenyl silicone oil has excellent performance, it is still necessary to regularly inspect the lubrication status and replenish or replace the lubricant in time.
Avoid contamination: Prevent moisture, impurities, etc. from entering the lubrication system and affecting the performance of phenyl silicone oil.
