Aerogel is a kind of porous material with nano structure, has unique properties in mechanics, acoustics, heat, optics and so on. They are obviously different from porous structure in micron and millimeter order porous materials, the fine nanostructure makes the thermal conductivity of materials very low, with a large specific surface area and other characteristics. There is have more than 80% air in aerogel, so it has very good heat insulation effect, and one inch thick aerogel is equivalent to 20 to 30 pieces of glass heat insulation function.

It can be applicable for outside clothes, sleeping bag, etc.
