Aerogel Powder
Aerogel powder represents the pinnacle of thermal insulation technology, offering exceptional performance in an ultra-lightweight format. Our engineered aerogel powders provide superior thermal management solutions across multiple industries, from aerospace to energy systems.
This hydrophobic aerogel powder features extremely low thermal conductivity (≤0.021 W/(m·k)) with bulk density of 55-65 kg/m³. With particle sizes ranging 50-100 μm and specific surface area of 800-1000 m²/g, it delivers optimal performance for applications requiring moisture resistance and thermal insulation.
Our finer hydrophobic variant offers the same exceptional thermal conductivity (≤0.021 W/(m·k)) with reduced bulk density (35-45 kg/m³). Featuring particles under 50 μm with 800-1000 m²/g surface area, this powder provides enhanced dispersion in composite materials.
Designed for applications requiring water absorption or compatibility, this hydrophilic silica aerogel powder maintains excellent thermal properties (≤0.025 W/(m·k)) with customizable particle sizing (0.1-5 μm) and broad density range (40-150 kg/m³).

Aerogel powder is primarily used as a functional filler in advanced insulation composites across multiple industries. It enhances thermal management systems, serves as phase change material carriers in thermal energy storage, improves polymer matrices in manufacturing, provides lightweight insulation for aerospace components, and creates efficient insulation solutions for construction and industrial equipment. The powder form allows for flexible integration into various materials and applications where traditional insulation formats are impractical.
Hydrophobic aerogel is created through surface modification processes where the naturally hydrophilic silica surface is treated with hydrophobic agents such as organosilanes. This chemical treatment replaces surface hydroxyl groups with non-polar organic groups, making the aerogel repel water while maintaining its porous structure and thermal properties. Our manufacturing process carefully controls this treatment to ensure consistent hydrophobic performance across all batches.
Silica aerogel can be either hydrophobic or hydrophilic depending on its surface treatment. Untreated silica aerogel is naturally hydrophilic due to surface hydroxyl groups that attract water. However, through chemical modification processes, silica aerogel can be made hydrophobic to resist moisture absorption. We offer both variants to meet different application requirements, with our hydrophobic versions maintaining their insulating properties even in humid environments.
While aerogel powder itself is chemically inert and non-toxic, proper handling precautions are necessary. The fine powder particles can cause temporary skin dryness or irritation in some individuals, similar to other fine powders. We recommend using appropriate personal protective equipment including gloves when handling large quantities. For applications involving direct skin contact in final products, the aerogel is typically encapsulated within composite materials, eliminating direct exposure concerns.
