Overview of Aerogel
Aerogel is a synthetic porous ultralight material, often derived from a silica gel, in which the liquid component has been replaced with a gas. This results in a solid with extremely low density and low thermal conductivity. Dubbed "frozen smoke" due to its semi-translucent appearance, aerogel is a marvel of materials science, offering a unique combination of properties that make it a cornerstone of advanced thermal and acoustic insulation solutions in the most demanding industrial environments.
Features of Aerogel
- Exceptional Thermal Performance: Boasts the lowest thermal conductivity of any known solid, providing unparalleled insulation in minimal space.
- Extremely Low Density: One of the world's lightest solid materials, with a porous structure that is over 90% air.
- Hydrophobic or Hydrophilic Formulations: Our aerogels can be engineered to either repel water (hydrophobic) for long-term performance or absorb it (hydrophilic) for specific applications.
- High Surface Area: With an internal surface area of up to 1000 m²/g, it is ideal for filtration, catalysis, and adsorption.
- Exceptional Durability: Flexible and robust, capable of withstanding significant mechanical stress and vibrational fatigue without compromising its insulating network.

5 FAQs of Aerogel
1. Is aerogel fragile?
While traditional monolithic aerogels can be brittle, our advanced industrial-grade aerogels are often reinforced with fibers or formulated into flexible blankets, making them highly durable and suitable for demanding industrial applications.
2. Can aerogel get wet?
Our standard industrial aerogel is hydrophobic, meaning it actively repels water. This ensures its insulating properties and structural integrity are maintained even after prolonged exposure to moisture.
3. Why is aerogel such a good insulator?
Its nanoporous structure (over 90% air) drastically limits the three methods of heat transfer: conduction, convection, and radiation. The air pockets are too small to effectively transfer heat.
4. Is aerogel safe to handle?
In its encapsulated or blanket form, it is safe and easy to handle like other high-performance insulation materials. As a powder, standard PPE for particulates is recommended.
5. What is the primary advantage over traditional insulation?
Its primary advantage is achieving superior thermal performance in a fraction of the thickness of traditional materials, saving critical space and weight in complex industrial systems.
