Specification of Hot Hydrophobic silica aerogel powder nano powder for thermal insulation

Hot hydrophobic silica aerogel powder is a high-performance nano material designed for advanced thermal insulation. This product is made of silica-based particles processed to create a lightweight, porous structure. The powder repels water effectively due to its hydrophobic treatment, making it suitable for moisture-prone environments. Its ultra-low thermal conductivity (around 0.015-0.025 W/m·K) ensures superior heat resistance, reducing energy loss in applications.

The primary component is amorphous silicon dioxide, forming a nanostructured network with over 90% porosity. This structure traps air molecules, minimizing heat transfer. The powder’s particle size ranges from 1 to 100 nanometers, allowing it to fill microscopic gaps. It operates effectively in temperatures from -50°C to 500°C, maintaining stability under extreme conditions.

This material is non-flammable and chemically inert, ensuring safety in industrial settings. Its low density (3-5 kg/m³) reduces weight in insulation systems. The hydrophobic property prevents clumping or performance loss when exposed to humidity. Applications include building insulation, pipe coatings, aerospace components, and protective gear.

The powder integrates easily into composites, paints, or textiles. It enhances thermal resistance without adding bulk. For construction, it improves energy efficiency in walls or roofs. In industrial equipment, it prevents heat loss in pipelines or storage tanks. Manufacturers use it to create thin, flexible insulation layers for electronics or automotive parts.

Packaging options include sealed containers to preserve quality. Storage requires a dry, cool environment. Users must wear protective gear during handling to avoid inhalation. Custom particle sizes or surface treatments are available for specific needs.

This product meets international safety and performance standards. It is eco-friendly, containing no harmful substances. Research continues to expand its use in renewable energy systems and high-tech industries. The combination of durability, efficiency, and adaptability makes it a preferred choice for modern thermal management solutions.

Applications of Hot Hydrophobic silica aerogel powder nano powder for thermal insulation

Hydrophobic silica aerogel powder is a lightweight nano material used widely for thermal insulation. This powder has high porosity and a nanostructure filled with air. These features give it extremely low thermal conductivity. It works better than traditional insulation materials like fiberglass or foam. The material is water-repellent due to its hydrophobic nature. This prevents moisture absorption, making it durable in humid conditions.

One main application is in the construction industry. The powder is added to coatings, plaster, or composite panels for buildings. It reduces heat transfer through walls, roofs, or windows. This helps maintain indoor temperatures. Energy costs drop because heating and cooling systems work less. The material’s thin layer saves space compared to bulkier insulation.

Industrial equipment also benefits from this aerogel. It insulates pipes, tanks, and machinery in factories or chemical plants. High-temperature processes require stable thermal management. The powder minimizes heat loss or gain in these systems. Its resistance to water avoids corrosion issues common in moist environments.

Transportation uses include insulating vehicles, aircraft, and ships. The lightweight property is critical here. Adding heavy insulation increases fuel consumption. The aerogel powder provides effective heat blocking without extra weight. Electric vehicle batteries use it to manage temperature during operation. This improves safety and performance.

The textile industry applies the powder to create heat-resistant fabrics. Outdoor clothing or gear lined with aerogel-infused layers traps body heat. This is useful for extreme cold environments. The material remains flexible, unlike rigid insulation options.

Electronics manufacturers use it to protect devices from overheating. The powder can be integrated into casings or components. It dissipates heat while keeping devices compact.

Hydrophobic silica aerogel powder adapts to many forms. It can be sprayed, mixed into liquids, or pressed into sheets. This versatility supports custom solutions across industries. Its nano-scale structure ensures consistent performance even in thin applications. The non-toxic, inert nature makes it safe for long-term use.

5 FAQs of Hot Hydrophobic silica aerogel powder nano powder for thermal insulation

What is hydrophobic silica aerogel powder?
Hydrophobic silica aerogel powder is a lightweight material made mostly of air. It has tiny pores that trap air molecules. This structure blocks heat transfer effectively. The powder repels water due to chemical treatment. It stays dry even in humid conditions. This makes it ideal for insulation in damp environments.

How does it provide thermal insulation?
The powder’s nanoporous structure slows heat movement. Air trapped in the pores acts as a barrier. Heat cannot pass through easily. The material’s low thermal conductivity keeps temperatures stable. It works better than traditional insulation like fiberglass. It requires less thickness to achieve the same effect.

Is it safe to handle?
The powder is non-toxic and chemically inert. Direct contact with skin poses minimal risk. Inhaling fine particles may cause irritation. Use protective gear like masks and gloves during handling. Store it in sealed containers to avoid spills. Follow standard safety guidelines for nanomaterials.

Where is it commonly used?
It’s used in construction for insulating walls and roofs. Industrial pipelines and equipment benefit from its heat resistance. Aerospace applications include insulating spacecraft components. It’s added to coatings or mixed into composites for better performance. Cold storage facilities use it to maintain low temperatures efficiently.

How should it be stored?
Keep the powder in a cool, dry place away from moisture. Exposure to water reduces its hydrophobic properties. Use airtight packaging to prevent contamination. Avoid high temperatures during storage. Check the powder for clumping before use. Proper storage ensures long-term effectiveness.
