Product properties
Unique nanoporous structure
The internal structure of aerogel is composed of cross-linked nanoparticles, which are connected to form a skeleton and form a unique porous network structure with an aperture of 20-50 nm. Therefore, aerogel has low density (≤ 0.16 mg/cm3), high specific surface area (400-1000 m2/g), high porosity (90%-99.8%) and low thermal conductivity (~ 0.012 WM-1K-1).
Aerogel has many excellent properties
Aerogel is a kind of material with nanoporous reticular structure. Due to its unique nanostructure, aerogel has unique excellent properties in thermal, acoustic, mechanical and optical aspects, and has many excellent properties such as thermal insulation, sound insulation and noise reduction, infrared absorption, catalysis and environmental protection.
