Introduction to Nano Aerogel Insulation

Nano aerogel insulation is an advanced material produced from aerogel with nano-scale structure, widely used since the 1990s. Aerogel is an extremely lightweight material derived from gel where liquid is replaced with CO₂ gas, resulting in a solid material with very light weight and high porosity. Nano aerogel’s distinctive feature is its nano-scale pores and structure, making it a highly efficient insulation material. This innovative insulation offers unique thermal protection unlike conventional insulation, being lightweight and versatile, particularly suitable for applications with thickness or weight constraints at temperatures between -200°C to 1000°C, such as in aviation, industry, and high-performance building insulation where value and space savings are paramount.

Key Properties of Nano Aerogel Insulation

1. Lowest Thermal Conductivity
   • Aerogel has one of the lowest thermal conductivity values, reaching as low as 0.01 W/m·K, ideal for temperature reduction applications
   • Nano-scale porous structure traps air, reducing heat transfer through convection and conduction, making it currently the most efficient thermal insulation
2. Light Weight
   • Aerogel consists of up to 99.8% air by volume, making it the lightest insulation material compared to conventional options
3. High Surface Area (Nano Porosity)
   • Nano-scale structure provides large surface area, enhancing both thermal and acoustic insulation efficiency
4. Hydrophobicity
   • Nano aerogel can be made water-repellent, providing moisture resistance and suitability for preventing CUI (Corrosion Under Insulation of Steel)
5. Flame Retardant
   • Non-flammable properties make it suitable for fire protection and high-risk environment insulation
6. Flexibility and Durability
   • Modern nano aerogel materials can be reinforced with fibers for increased durability and flexibility, ensuring long service life and investment value

Applications of Nano Aerogel

1. Building Insulation
   • Used in walls, windows, and roofs for maximum thermal protection while saving space
2. Aviation and Automotive Industries
   • Widely used in spacecraft, aircraft, combustion vehicles, and electric vehicles requiring thin, excellent thermal insulation that’s lightweight and efficient
3. Oil and Gas Industry
   • Used for pipes, storage tanks, and equipment insulation in extreme weather conditions
4. Clothing and Wearable Equipment
   • Found in winter clothing, gloves, and boots for thermal protection without adding weight or bulk
5. Electronic Equipment
   • Protects sensitive electronic components from temperature changes and heat damage
6. Cryogenic Technology
   • Used in cryogenic storage systems and cold chain transportation

Advantages Over Traditional Insulation
