How are silicones used in Aerospace applications?
CHT have been supplying and supporting the aerospace industry for over 40 years. Our Silcoset® brand is well respected and approved by many aerospace companies.
Silicones now have a proven record of long term performance in the most demanding applications, offering the following general physical attributes:
- Wide temperature range from -115 to 300ºC
- Excellent electrical properties
- Flexibility
- UV resistance
- Good chemical resistance
- Resistance to humidity and water
- Non-toxic and inert
Our Silcoset® range includes 1-part silicone adhesive sealants and 2-part silicone encapsulants.
With the development of new technologies, we are now able to offer our AS1800 range of neutral cure RTV's with a measure of fuel resistance, high thermal conductivity and temperature resistance.
The CHT encapsulant range includes materials that can withstand operating temperatures between -155°C and +300°C, high purity gels and have high thermal conductivity.
Applications Include:
- Avionics - displays, electronics, lighting
- Aero engine - damping, bonding, sealing
- Airframe - sealing, bonding
