Unique advantages and application scenarios of rubber and plastic seals in the aerospace field

As a key sealing material, rubber and plastic seals play an important role in the aerospace field. This article will explore in depth the unique advantages of rubber and plastic seals in the aerospace field and their application scenarios.

1. Lightweight design

In the aerospace field, the weight of the aircraft is crucial to its performance. Rubber and plastic seals are lightweight and soft, which can achieve lightweight design, reduce the overall weight of the aircraft, and improve fuel efficiency and flight performance.

2. Good sealing performance

The requirements for seals in the aerospace field are very strict, and they need to be able to maintain a stable sealing effect under extreme conditions. Rubber and plastic seals have good elasticity and deformation ability, can adapt to different temperature, pressure and vibration environments, and ensure that the sealing effect of various parts of the aircraft is stable and reliable.

3. High temperature and low temperature resistance

In space flight, the aircraft may experience extreme temperature changes, and the seals need to have good high temperature and low temperature resistance. Rubber and plastic seals are usually made of high temperature resistant materials, which can maintain good sealing effects in high and low temperature environments to ensure the normal operation of the aircraft.

4. Chemical corrosion resistance

Equipment and systems in the aerospace field are usually exposed to various chemical media, and seals are required to have good chemical corrosion resistance. Rubber and plastic seals are usually made of corrosion-resistant rubber or silicone materials, which can be used stably for a long time in different chemical media to ensure the safe operation of aircraft.

Application scenarios

Engine seals: Rubber and plastic seals are widely used in lubrication systems, fuel systems, cooling systems and other parts of aircraft engines to prevent liquid or gas leakage and ensure the normal operation of the engine.

Aerospace seals: In the hatches, portholes, doors and other parts of aerospace, rubber and plastic seals are used as sealing gaskets or sealing strips to ensure the sealing and safety of aerospace.

Aerospace fuel system seals: In the fuel system of aerospace, rubber and plastic seals are used as oil seals, O-rings and other components to prevent fuel leakage and ensure the safe operation of the fuel system.

In summary, rubber and plastic seals have unique advantages in the aerospace field, including lightweight design, good sealing performance, high and low temperature resistance, and chemical corrosion resistance. They are widely used in key parts such as aircraft engines, aerospace vehicles, and fuel systems, providing strong support for the development and progress of the aerospace field.
