1.Ultra-low Thermal Conductivity：Silica aerogel powder exhibits extremely low thermal conductivity, effectively reducing heat transfer and providing superior insulation performance.
2.Very Low Density：With an exceptionally low bulk density, it enables lightweight material design without compromising insulation efficiency.
3.Nanoporous Structure：The material contains a highly developed three-dimensional nanoporous network that traps air at the nanoscale, significantly suppressing heat convection.
4.Excellent Thermal Stability：It maintains structural and functional stability over a wide temperature range, typically from cryogenic conditions up to high temperatures.
5.Hydrophobic Surface (Optional)：Surface-modified silica aerogel powder can be highly hydrophobic, minimizing moisture absorption and maintaining insulation performance in humid environments.
6.High Specific Surface Area：The large internal surface area enhances its interaction with binders and matrices, improving dispersion in composite systems.
7.Chemical Inertness：The material is chemically stable, resistant to acids, alkalis, and aging, and does not easily degrade under harsh conditions.
8.Good Processability as a Functional Filler：Its powder form allows easy incorporation into coatings, polymers, cementitious systems, and other composite materials.
9.Non-combustible and Environmentally Friendly：Silica aerogel powder is non-flammable, non-toxic, and free of hazardous emissions.
10.Customizable Properties：Particle size, density, hydrophobicity, and surface treatment can be tailored to meet specific application requirements.

FAQ
1.What is the difference between silica aerogel powder, granules, and blankets?
Silica aerogel powder is mainly used as a functional filler in composite materials. Granules are suitable for loose-fill insulation or molded parts, while aerogel blankets or boards are finished insulation products used directly in industrial or construction applications.
2.What are the main applications of silica aerogel powder?
It is widely used in thermal insulation coatings, high-temperature insulation materials, industrial pipelines, energy storage systems, construction materials, and thermal management solutions.
3.Is silica aerogel powder safe to use?
Silica aerogel powder is non-toxic and non-carcinogenic. However, due to its fine particle size, appropriate dust protection measures such as masks and ventilation are recommended during handling.
4.What is the difference between hydrophobic and hydrophilic aerogel powder?
Hydrophobic aerogel powder repels moisture and is suitable for humid or outdoor environments, while hydrophilic aerogel powder is used in water-based systems or applications requiring higher surface polarity.
