AG-DC hydrophobic Silica Aerogel Powder

Traditional thermal insulation materials such as mineral wool, fiberglass, perlite, polyurethane foam, and calcium silicate have long been used across construction, industrial insulation, and energy systems. However, as global energy efficiency standards become stricter and equipment operates under more extreme temperature conditions, these conventional materials are increasingly facing critical limitations:

Excessively high thermal conductivity that fails to meet modern energy-saving requirements

Excessive thickness requirement to achieve target insulation performance

Moisture absorption and irreversible performance degradation over service life

Poor fire resistance in polymer-based formulations, raising safety risks

Inability to adapt to space constraints in retrofitting projects and compact system designs

Weak durability under high-temperature or cyclic thermal environments

As a leading China aerogel manufacturer with 1100 tons of annual silica aerogel powder production capacity, we see a clear industry shift:

in building envelopes, LNG storage, battery thermal protection, industrial pipelines and more, the market demand is moving toward high-performance, ultra-thin, lightweight, and long-lasting insulation solutions. This is where our hydrophobic silica aerogel powder delivers a game-changing technological advancement.

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

This innovative structure gives our silica aerogel powder exceptional thermal insulation performance that far surpasses conventional insulation materials, while our mass production capacity ensures stable batch-to-batch consistency for global bulk orders.

Key Performance Advantages of AG-DC Silica Aerogel Powder

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

As an inorganic silica-based material, our aerogel powder 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, our aerogel powder 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

With an extremely low bulk density, our aerogel powder significantly reduces structural load while maintaining excellent insulation efficiency. Its ultra-thin application profile perfectly solves the space constraint challenges in retrofitting projects and compact system designs that traditional thick insulation materials cannot address.

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.
