The lubrication demand of phenyl silicone oil in the aerospace field is mainly reflected in its unique performance advantages and the high requirements of aerospace equipment for lubricants.

1. Performance advantages of phenyl silicone oil
High and low temperature resistance:
Phenyl silicone oil has excellent high and low temperature resistance and can maintain stable lubrication effect under extreme temperature conditions.
Low phenyl silicone oil has significant low temperature resistance and is also fluid at -70℃.
High phenyl silicone oil has high thermal stability and only oxidizes when heated above 250℃, and the viscosity increases.
Lubrication performance:
Phenyl silicone oil has good lubrication performance and can significantly reduce the friction coefficient and wear rate.
With the increase of phenyl mole fraction, the lubricity and solubility of silicone oil in organic solvents are improved.
Chemical stability:
Phenyl silicone oil has high oxidation stability, heat resistance, flame resistance, UV resistance and chemical resistance.
It can maintain stable lubrication performance in harsh chemical environments.
Electrical properties:
Phenyl silicone oil has excellent electrical insulation properties and is suitable for aerospace equipment requiring high electrical insulation.

2. Requirements for lubricants in aerospace equipment

High reliability:
Aerospace equipment has extremely high requirements for the reliability of lubricants, because any lubrication failure may cause equipment failure or accident.

Phenyl silicone oil, with its stable performance and long life, can meet the high reliability requirements of aerospace equipment.

Wide temperature range:
Aerospace equipment works under extreme temperature conditions, requiring lubricants to maintain stable lubrication effects over a wide temperature range.

The high and low temperature resistance of phenyl silicone oil makes it an ideal choice for aerospace equipment.

Chemical compatibility:
The materials used in aerospace equipment are diverse, requiring lubricants to have good chemical compatibility with these materials.

Phenyl silicone oil is compatible with a variety of materials and will not cause chemical reactions or corrosion.

Low volatility:
Aerospace equipment has strict requirements for the volatility of lubricants, because lubricants with high volatility will fail quickly and may contaminate the equipment.

Phenyl silicone oil has low volatility and can maintain a stable lubrication effect in the equipment for a long time.

In summary, phenyl silicone oil has a wide range of lubrication needs in the aerospace field, with its unique performance advantages and the high requirements of aerospace equipment for lubricants.
