Aerogel Insulation Film is  is a kind of Special thermal insulation material, which is mostly used for thermal insulation and thermal insulation. It,s composition is mainly silica aerogel. It has ultra-low thermal conductivity and a good thermal insulation effect,based on aerogel water-based slurry and is a film-shaped nano-thermal insulation material prepared by fine coating technology on a variety of functional optional substrates. It aims to solve the thermal management problems of uniform heat and heat dissipation of precision industrial products in a small space, especially for weak heat-resistant components, which have a good heat insulation protection effect, improve the comfort of use of electronic products, and prolong the service life of electronic products.It is a class of low-density solid gels in which the liquid has been replaced with air or gas. The structural framework of Aerogel is typically composed of silica, so silica aerogel is often referred to as simply “Aerogel.” However, other structural materials have been used to create aerogels.
