Aerogel helps the aerospace field reach new heights
As a globally leading new type of thermal insulation material, Aerogel is gradually becoming an important technical support in the fields of aerospace thermal insulation and high-performance thermal insulation. Aerogel, with its outstanding thermal insulation performance and resistance to extreme environments, is widely used in critical parts such as insulation layers of spacecraft, satellite protection, and insulation in aircraft engine compartments.
NASA in the United States has successfully applied aerogel to the insulation system of Mars probes and used it to capture comet dust particles, demonstrating the unique value of aerogel in deep space exploration. Meanwhile, the lightweight properties of aerogel materials also help spacecraft reduce overall weight, improve fuel utilization efficiency, and aerogel is lighter, smaller in volume and has a higher space utilization rate than traditional insulation materials.
Aerogel for Aerospace
Aerogel is widely regarded as one of the most advanced thermal protection materials in aerospace engineering, offering unmatched insulation in an ultra-light, highly porous solid. Its extremely low density, superior thermal resistance, and ability to perform in extreme temperature environments make it ideal for spacecraft, satellites, high-altitude aircraft, and thermal-sensitive aerospace components. Aerogel is used in blankets, panels, coatings, and structural composites to provide reliable thermal control, protect instruments, and reduce overall system weight—critical advantages in aerospace design where every gram matters.
Its capacity to maintain insulation at both cryogenic and high-temperature extremes, while resisting radiation and minimizing outgassing, allows aerogel to solve challenges such as heat shielding, cryogenic fuel containment, thermal stability in vacuum, and temperature management for sensitive electronics.
Spacecraft Thermal Protection Systems (TPS): Used as part of multilayer insulation for spacecraft exteriors to protect against extreme cold in deep space and intense heating during solar exposure.
Satellite Thermal Control: Integrated into panels and blankets to maintain stable temperatures for sensors, batteries, and onboard electronics in vacuum environments.
Cryogenic Propellant Tanks: Provides efficient insulation for liquid hydrogen, oxygen, and other cryogenic fuels, reducing boil-off and maintaining structural temperature stability.
Re-entry and High-Temperature Insulation: Applied in heat shields and protective layers to reduce thermal shock during atmospheric re-entry or high-speed flight conditions.
Aviation & High-Altitude Platforms: Used in UAVs, high-altitude balloons, and aircraft components to maintain performance in low-pressure, low-temperature environments.
Instrument & Payload Protection: Safeguards scientific instruments from temperature fluctuations, vibration, and thermal gradients during missions.
Thermal Performance: Offers one of the lowest thermal conductivities of any solid, enabling effective insulation in vacuum, cryogenic, and high-temperature conditions.
Ultra-Lightweight: Provides major weight savings in spacecraft and aircraft systems, where mass reduction directly boosts performance and reduces launch costs.
Wide Temperature Operating Range: Maintains performance from cryogenic temperatures below –200°C to high-temperature environments above 600°C, depending on formulation.
Environmental Stability:v Low outgassing, hydrophobic options, and radiation resistance make aerogel suitable for long-duration missions.
Design Flexibility: Available as flexible blankets, rigid panels, composites, granules, and coatings for integration into diverse aerospace components.
Aerogel consists of up to 99.8% air contained within a nanoporous silica or polymer matrix. This structure significantly restricts heat transfer through conduction, convection, and radiation. Aerogel is created by replacing the liquid component of a gel with gas through supercritical drying, resulting in an ultra-light solid with exceptional insulating properties. This unique composition enables high performance in vacuum, extreme temperatures, and rapid thermal shift environments common in aerospace applications.
