Aerogel heat insulation film is a kind of heat insulation material, which is mainly used for heat preservation and heat insulation. Its composition is mainly silica aerogel, its color is white by visual inspection, and its thickness is generally 0.05~0.3 mm. Air gel thermal insulation film is a new type of air gel film like thermal insulation nano material, which helps customers solve the heat equalization problem in the narrow space of consumer electronics products and protect weak heat resistant electronic components, improve the performance and service life of products, and improve the comfort of human body. It can be combined with high thermal conductivity materials such as graphite film to provide various heat dissipation solutions. Mainly used in consumer electronics products such as wearable terminals, smartphones, laptops, tablets, and smart TVs.
