Key Advantages of custom Aerogel Powder
Ultra-Low Conductivity
The nanoporous structure of aerogel powder effectively suppresses solid heat transfer and gas convection. When incorporated into coatings or composite systems, aerogel powder significantly reduces thermal conductivity and improves insulation performance.
High Surface Area
Aerogel powder provides extremely high specific surface area, offering abundant interfacial contact for adsorption, catalytic reactions, and material bonding in composite systems.
Lightweight Filler
With very low bulk density, aerogel powder serves as an ideal lightweight functional filler. It enhances thermal performance while maintaining low material weight.
Easy Dispersion
Hydrophilic aerogel powder contains surface silanol groups that enable stable dispersion in water-based and inorganic systems, allowing efficient integration into various industrial formulations.
