Silicones in Aerospace

Silicone is widely used in the aerospace industry based on its durability, sealing properties, stability across an extreme temperature range, naturally flame retardant properties, and sound dampening and vibration resistance,. Keeping extreme functionality is critical to passenger safety in the aerospace industry, hence each component on an aircraft requires high-performance materials.

 

Specially designed aerospace grades of silicone stabilized at −70 °C to 220 °C, these grades can be used in the construction of gaskets for windows and cabin doors. During operation, the aircraft suffers large temperature fluctuations in a relatively short time; from freezing temperatures at full altitude to ambient temperatures on the ground in hot countries. Silicone rubber can be molded for tight tolerances ensuring gaskets form an airtight seal on the ground and in the air where atmospheric pressure decreases.

 

SiSiB silicone rubber's heat-resistant corrosion properties make it more durable than other types of rubber for gaskets used in aircraft engines, improving safety and reducing maintenance costs. The silicone acts as a seal to cockpit dashboards and other electrical systems, avoiding printed circuit boards from the risk of extreme altitude like humidity and extremely low temperatures.

 

Due to the nature of air travel will cause much noise and vibration, powerful engines, landings and high speeds all need to be considered to make sure that passenger comfort and safe operation of the aircraft. Due to silicone rubber has excellent noise reduction and vibration resistance, it can be formed into widgets and installed in small gaps to ensure that all equipment can be avoided from unnecessary vibration, such as exhaust pipes, hatches, entertainment system seals, overhead lockers and LED lighting systems.
