AG-DC Hydrophobic silica Aerogel Powder

Traditional insulation materials such as mineral wool, fiberglass, polyurethane foam, and calcium silicate are widely used in construction and industrial thermal management. However, many conventional materials face limitations in thermal efficiency, moisture resistance, fire safety, durability, and space-saving applications under increasingly demanding energy and operating conditions.

As energy efficiency standards continue to rise across building envelopes, battery thermal protection, and industrial insulation systems, the market is shifting toward thinner, lighter, and higher-performance insulation solutions. Our hydrophobic silica aerogel powder is designed to meet these next-generation thermal management requirements.

What is Hydrophobic Silica Aerogel Powder?

Hydrophobic silica aerogel powder is a nanoporous solid insulation material, derived from high-purity silica gel through a controlled supercritical drying process. With an ultra-high porosity of 90–99% and a stable three-dimensional nano-network structure, it is widely recognized as one of the lowest thermal conductivity solid materials available for industrial mass production today.

Its unique nano-scale pore structure effectively suppresses all three forms of heat transfer:

Solid heat conduction through the nano-silica skeleton

Gas convection within pores smaller than the mean free path of air molecules

Infrared radiation heat transfer at high temperatures

                Nanoporous structure of our industrial hydrophobic silica aerogel powder

This innovative structure gives aerogel exceptional thermal insulation performance that far surpasses conventional insulation material.

Key Performance Advantages 

Ultra-Low Thermal Conductivity

Industry-leading thermal conductivity of 0.012–0.016 W/(m·K) @ 25°C, up to 3-5 times more efficient than traditional insulation materials, delivering superior thermal performance with minimal thickness.

Exceptional High-Temperature Stability & Fire Safety

This inorganic silica-based material is inherently non-combustible, helping composite systems achieve top fire safety ratings including UL 94 V-0 and EN 13501-1. It maintains stable performance under long-term high-temperature operating conditions, solving the durability issue of conventional materials in cyclic thermal environments.

Permanent Hydrophobic Performance

With a proprietary surface hydrophobic treatment, the product achieves ≥99% water repellency, completely preventing moisture absorption and performance degradation over its service life, even in high-humidity industrial and outdoor environments.

Ultra-Lightweight & Space-Saving

Marginally heavier than air, the material delivers exceptional thermal insulation performance at an ultra-low density, drastically reducing structural load compared to traditional insulation materials. Its 

ultra-thin profile further eliminates the space constraints that bulky conventional solutions cannot address in retrofits and compact system designs.

Scalable Composite Applications of Silica Aerogel Powder

While monolithic aerogel has inherent brittleness, our aerogel powder is engineered for seamless integration into a wide range of material systems. It acts as a high-performance functional insulating filler, allowing manufacturers to upgrade their existing products without fundamentally changing their base structure or processing methods.
