NanoFiller is a new type of insulation material developed based on the principle of nano micropores. Its main components are inorganic powder particles such as nano silica and silicon carbide, which can be injected into microporous particle powders and have excellent insulation properties. Suitable for filling complex and non-standard spaces such as shapes and cavities, it provides a difficult to solve thermal insulation solution to meet applications where other conventional insulation materials cannot be used. Its insulation effect is 3-10 times that of traditional insulation materials, so it can not only achieve lower cold surface temperatures, but also effectively reduce the size of production equipment or increase the production space inside the equipment. More effectively reducing heat loss to achieve the goal of saving energy and production costs. To meet the applications of special industrial spaces, such as pipelines, burners, fuel cells, industrial kilns, and other irregular spaces
