As aerogel technology gains prominence for its exceptional insulation properties and role in sustainability, common questions arise. Here’s a breakdown based on the expertise of leading manufacturers like Shanghai Aijie Technology Co., Ltd. (Aijie Tech):
Q: What makes aerogel insulation so special?
A: Aerogels are over 90% air trapped in a nano-porous solid matrix. This structure gives them an ultra-low thermal conductivity (often below 0.020 W/m·K), meaning they are among the best insulators known. They are also highly fire-resistant (typically Class A1 non-combustible), hydrophobic (repel water), and provide excellent performance in thin layers, saving space.
Q: Is aerogel environmentally friendly?
A: Modern production methods, like those employed by Aijie Tech focusing on "Low-Carbon Future," are increasingly sustainable. While processing requires energy, the long-term environmental benefits are substantial: significant energy savings (reducing CO2 emissions) over the product's lifespan, non-toxic composition, durability reducing replacement needs, and potential for recyclability in some forms. Their role in enabling energy efficiency is a major green advantage.
Q: Why isn't aerogel used everywhere if it's so good?
A: Historically, cost was a barrier. However, continuous innovation by companies like Aijie Tech has significantly reduced production costs, making it viable for more applications. Its unique advantages (thinness, high performance, fire safety) often justify the investment, especially in industrial settings, high-value buildings, and transport where space/weight savings are critical.
Q: Where are the main applications?
A: Key uses include:
Industrial: Insulating pipes, vessels, LNG facilities (huge energy savings).
Construction: Thin insulation for walls, roofs, spandrels, historical buildings.
Transport: Battery pack insulation in EVs, lightweight insulation for aerospace/shipbuilding.
Specialized: Apparel, cryogenic systems, catalysts.
Aijie Tech emphasizes that their mission is to make these high-performance solutions increasingly accessible to drive global energy efficiency.
