As a game-changer in the insulation industry, aerogel has broken 15 Guinness World Records with its unparalleled properties—from the lowest thermal conductivity to the lowest density. To help you unlock its full potential, we've compiled the most critical FAQs for industrial partners, builders, and innovators:
Q1: What exactly is aerogel?
A: Aerogel is a family of nanoporous solid materials, with silica (SiO₂) aerogel being the most widely used. Composed of a nano-scale 3D network filled with 3-95% air, it’s the lightest solid material on Earth to date.
Q2: Is aerogel a sticky "gel"?
A: Not at all! It’s a dry, powdery solid nicknamed "solid smoke" or "blue smoke." The name comes from its production process—supercritical drying transforms wet gel into the dry, porous aerogel we use.
Q3: Is aerogel toxic or harmful?
A: 100% inorganic and non-toxic (silica aerogel is made of air and SiO₂). The only caution: aerogel dust may cause temporary skin/eye irritation. We recommend wearing protective gear (mask, gloves, goggles) during handling.
Q4: Why is it called a "future material"?
A: Its record-breaking properties (e.g., ultra-low thermal conductivity) make it irreplaceable for high-performance insulation. As research advances, new applications are constantly emerging across industries.
Q5: What are common aerogel materials?
A: Silica aerogel composites (flexible blankets, rigid boards, encapsulated thermal barriers) and pure silica aerogel powder/granules.
Q6: Is aerogel insulation blanket pure aerogel?
A: No—it’s a composite! Compounded with glass/ceramic fiber blankets, it delivers better mechanical strength and lower thermal conductivity than pure aerogel or fibers alone.
Q7: Why use composites instead of 100% pure aerogel?
A: Pure aerogel is extremely brittle. Compounding with high-strength substrates solves this, making it practical for real-world applications.
Q8: What makes it the "ultimate insulation material"?
A: It blocks all three heat transfer mechanisms:
• Conduction: Nano-porous structure creates ultra-long heat paths.
• Radiation: Gas-solid interfaces reflect/absorb thermal radiation.
• Convection: Pores <70nm restrict gas molecule movement.
Q9: Is aerogel mass-produced for civil use?
A: Absolutely! Mature for decades, our proprietary production process solves dust-shedding issues and enables cost-effective industrialization. It’s widely used in oil & gas, construction, EVs, and more.
Q10: Why is it expensive? Is it cheaper than before?
A: Prices have dropped 50% in China over 10 years, but remain higher than traditional materials due to complex production (sol-gel + supercritical drying) and high-quality raw material/operator requirements.
Q11: Key applications today?
A: Industrial insulation (high/low/ultra-high temperature), building construction (walls/roofs/HVAC), energy storage, and EV battery thermal management (fire protection + thermal runaway prevention).
Q12: Civil-use aerogel materials?
• Flexible blankets (≤650℃ for industrial/construction; -200℃~+400℃ for low-temperature storage).
• Rigid boards (≤650℃ for general use; ≤1500℃ for ultra-high temperature equipment).
• Powder/granules (additives for insulation coatings, mortars, plastics).
Q13: Pros & Cons
✅ Advantages:
• Ultra-low thermal conductivity (even at 650℃).
• Thin insulation layer (1/5~1/3 of traditional materials) + easy installation.
• Waterproof (hydrophobicity ≥98%), flame-retardant (Class A), non-toxic.
• Durable (same lifespan as equipment/pipelines) + reusable.
❌ Disadvantages:
• Higher cost than traditional insulation.
• Dust shedding (solved by our low-dust technology for clean environments).
Q14: Key properties to check when buying?
Thermal conductivity, operating temperature range, dust shedding rate, hydrophobicity, combustion rating, density, and flexibility/stiffness (tailored to your application).
Q15: How do thickness, thermal conductivity relate to insulation effect?
• Thermal conductivity is material-specific (unrelated to thickness).
• Same material: Thicker = better insulation.
• Same thickness: Lower thermal conductivity = better insulation.
