Overview of Hydrophobic/Hydrophilic Silicon Aerogel Sio2 Thermal Insulation Powder/Particle
Aerogel powder is the granular form of the world’s lightest solid material, often called “frozen smoke.” This nanoporous substance is created by replacing the liquid in a gel with gas, resulting in an ultra-low-density solid with extraordinary properties. Our aerogel powder retains the exceptional qualities of monolithic aerogels in a versatile, easy-to-integrate format for diverse industrial and research applications.

Hydrophobic/Hydrophilic Silicon Aerogel SiO ₂ Thermal Insulation Powder
Ultra-Lightweight, High-Performance Insulation Product
This silicon dioxide (SiO ₂) aerogel powder provides phenomenal thermal insulation in a light-weight, simple kind. It is used innovative sol-gel modern technology and supercritical drying to create a nanoporous structure with as much as 95% air material. The outcome is one of the lightest strong materials known, providing extremely low thermal conductivity– usually in between 0.013 and 0.018 W/( m · K)– also at heats.
The item comes in 2 surface therapies: hydrophobic and hydrophilic . The hydrophobic variation repels water and stands up to wetness absorption, making it ideal for outdoor or humid settings. The hydrophilic variation readily bonds with water-based systems and works well in coatings, compounds, or cementitious formulations where solid integration is needed.
Its great particle size enables smooth blending into paints, plasters, adhesives, and polymer matrices without jeopardizing flow or workability. Regardless of its delicate nanostructure, the powder maintains architectural integrity under normal handling and processing problems.
Key Features:
– Very reduced thermal conductivity
– Very reduced density (as low as 0.08 g/cm ³).
– High particular surface (500– 800 m ²/ g).
– Chemically inert and safe.
– Secure up to 650 ° C in air.
Usual Applications:
– Insulating finishes for structures and pipes.
– Ingredient in building and construction products like renders and boards.
– Filler in fire-resistant fabrics and compounds.
– Thermal barriers in devices and commercial equipment.
Both hydrophobic and hydrophilic versions fulfill rigorous high quality standards for pureness and performance uniformity. They are supplied in covered product packaging to protect their nanostructure and stop dampness uptake before use. This aerogel powder offers engineers and formulators a flexible, high-efficiency solution for next-generation thermal management.

Applications of Hydrophobic/Hydrophilic Silicon Aerogel SiO₂ Thermal Insulation Powder
Building and Construction
Silicon aerogel powder is widely used in walls, roofs, and floors to reduce heat loss. Its ultra-low thermal conductivity helps buildings stay warm in winter and cool in summer. The hydrophobic version resists moisture, which keeps insulation performance stable over time. This makes it ideal for humid climates or areas prone to rain.
Industrial Equipment
Pipes, tanks, and reactors often operate at high or low temperatures. Adding SiO₂ aerogel particles to insulation jackets cuts energy waste and improves safety. The hydrophilic type bonds well with water-based coatings, while the hydrophobic form works better in oily or damp environments. Both help lower operational costs and meet energy efficiency standards.
Apparel and Outdoor Gear
Outdoor clothing, sleeping bags, and footwear now use aerogel-infused fabrics. The powder adds warmth without bulk. Hydrophobic aerogel repels sweat and rain, keeping users dry and comfortable. It’s especially useful in extreme cold where traditional insulators fail.
Transportation
Cars, trains, and aircraft use this material to insulate cabins and engine compartments. Lightweight and thin, silicon aerogel powder saves space and reduces fuel consumption. In electric vehicles, it also protects battery packs from temperature swings, boosting performance and lifespan.
Consumer Electronics
Smartphones, laptops, and wearables generate heat during use. A thin layer of aerogel powder inside the device acts as a thermal barrier. It prevents overheating without adding weight. The hydrophobic variant guards against humidity damage, which is common in tropical regions.
This versatile insulation material meets modern demands for efficiency, durability, and compact design across many industries.

5 FAQs of Hydrophobic/Hydrophilic Silicon Aerogel Sio2 Thermal Insulation Powder/Particle
Frequently Asked Questions About Hydrophobic/Hydrophilic SiO₂ Aerogel Insulation Powder
What is hydrophobic vs. hydrophilic aerogel powder?
Hydrophobic aerogel repels water. It stays dry even in wet conditions. Hydrophilic aerogel absorbs moisture from the air. Both types are made from silica (SiO₂) but treated differently to control how they interact with water.
Why choose hydrophobic aerogel for insulation?
Hydrophobic aerogel keeps its insulating power when exposed to humidity or rain. Water can ruin thermal performance. Since this type resists moisture, it works better outdoors or in damp places like pipes, roofs, or marine equipment.
When is hydrophilic aerogel preferred?
Hydrophilic aerogel is often used indoors or in sealed systems where moisture is not a concern. It bonds well with certain binders and coatings. This makes it useful in composites, paints, or lab applications that need strong integration with other materials.
How does aerogel powder provide thermal insulation?
Aerogel has a very porous structure filled with air. Air slows down heat transfer. The tiny pores block conduction and convection. That’s why even a thin layer of aerogel powder gives excellent insulation with minimal weight.
Is aerogel powder safe to handle?
Yes, silica aerogel powder is non-toxic and chemically stable. Still, wear gloves and a mask during handling. Fine particles can irritate skin or lungs. Store it in a dry place, especially the hydrophilic kind, to avoid clumping or performance loss.
