Silicones resist high temperatures and their physical characteristics vary very little, even under extreme temperature conditions, which is why many industrial fluids are formulated with silicone as a base.
Fluids that convey heat are used to heat or cool chemical reactors and to produce constant temperature baths used to test measuring devices that must function at high temperatures. They are also used to cool and insulate medium-power transformers that supply our towns and industries with electricity.
The thermal stability of silicones stems from the thermally stable Si-O and Si-CH3 bonds themselves. However, the partially ionic nature of these bonds (51%) means that they can be destroyed by concentrated acids and alkalis at ambient temperatures.
"As a result, silicones are used in a wide range of applications relying on thermal stability, for example airplanes."
Airplanes can take off in the desert at very high temperatures and then fly at an altitude of 10.000 meters where temperatures are extremely low with no impact on performance or safety.
