Momentive Silicone technologies offer several advantages that make it useful in aerospace, including:
Thermal versatility
-
Silicone can withstand both high and low temperatures, remaining flexible and elastic from -58°F to 392°F (-50°C to 200°C).
Chemical resistance
-
Silicone’s chemical properties can't be altered once it's heated and crosslinked, so it maintains its properties in a wide range of environmental conditions.
Electrical properties
-
Silicone’s electrical properties make it ideal for insulation and protecting precise conductivity.
Low viscosity
-
Silicone’s low viscosity and ease of metering make it ideal for precise molding.
Aerospace Applications
- Seals and gaskets
Because LSR can withstand temperatures ranging from -50°C to 200°, it is an excellent material to use for sealing important aeronautical parts. Cabin windows, fuel systems, hydraulic lines, landing gear, and other components can all use LSR gaskets or seals are designed to withstand severe weather and high pressure.
-
Electric insulation
When it comes to insulating electrical components in aeronautical applications, LSR offers outstanding dielectric properties and thermal stability. LSR provides consistent protection against moisture, chemicals, and temperature changes, ensuring that avionics systems last.
-
Structural elements
In the aircraft manufacturing industry, lightweight structural components are of the utmost importance. LSR’s inherent lightweight and molding properties make it a desirable choice when designing aircraft components.
-
Vibration dampening
Reducing vibrations and harshness is critical in aircraft and aerospace applications to reduce disturbances and enhance overall passenger comfort. HCR offers excellent tear strength and flexibility that effectively helps to reduce vibrations by absorbing shock in essential aircraft components and engine mounts.
-
Thermal management
Because silicone elastomers can endure temperatures as high as -50°C to 200°C, they provide excellent thermal control in aircraft engines, avionics, and cabin systems. HCR offers exceptional thermal and weatherability performance in applications like electronic enclosures and insulation.
