The special applications of silicone in the aerospace field are very extensive, mainly reflected in the following aspects:

1. High temperature resistance and thermal insulation performance
High temperature resistant parts: Silicone materials have excellent high temperature resistance and can maintain good physical and chemical properties in high temperature environments. This makes it very suitable for manufacturing high temperature parts in the aerospace field, such as jet engine parts, rocket engine parts, etc. These parts can continue to work stably in high temperature environments to ensure the safe operation of aerospace vehicles.
Insulation materials: Silicone materials have low thermal conductivity and excellent thermal insulation properties, and can be used to make thermal insulation materials for aircraft. This material can effectively reduce heat conduction, protect the internal structure and equipment of the aircraft from high temperature, and ensure the normal operation of the aircraft.

2. Sealing and leakproofing
Seals: Silicone materials are widely used in the aerospace field to manufacture various seals, such as engine seals, pipe seals, hatch seals, etc. These seals have excellent high temperature resistance, low temperature resistance, and corrosion resistance, which can ensure the stability and safety of the internal environment of aerospace vehicles and prevent the penetration of liquids and gases.
Sealing coating: Silicone sealing coating can prevent the penetration of liquids and gases and protect metal surfaces from corrosion. The application of this coating in the aerospace field can significantly improve the reliability and service life of equipment.

3. Lubrication and drag reduction
Lubricant: Silicone lubricant has excellent high temperature resistance and chemical stability, and can provide good lubrication under extreme conditions. In the aerospace field, this lubricant is widely used in the lubrication of engines and other mechanical parts to reduce wear and friction and extend the service life of mechanical parts.

Drag reduction coating: Silicone materials have low surface energy and low friction coefficient and can be used to manufacture the outer surface coating of aircraft and rockets. This coating can reduce air resistance, increase flight speed and fuel efficiency. At the same time, silicone materials can also be used to manufacture various drag reduction components, such as fairings, flaps, etc., to further reduce air resistance.
