Thermal insulation performance of nano aerogel felt? Industrial thermal insulation nano aerogel mat is a flexible thermal insulation material composed of nano aerogel and reinforced fiber substrate (such as glass fiber, ceramic fiber, pre oxidized fiber mat). Nano aerogel felt is one of the most excellent flexible thermal insulation materials in the world, known as "solid smoke" or "ultimate thermal insulation material". Its core is composed of a nano porous network structure of silicon dioxide (SiO ₂), with a porosity of up to 90% -99% and a pore size smaller than the average free path of air molecules (<70 nm), greatly suppressing the three heat transfer modes of heat conduction, convection, and radiation.
