Cesium tungsten bronze may be applied for producing thermal insulation masterbatch --- a kind of dingal masterbatch, which has the performance of shielding ultraviolet and near-infrared rays. It is also a kind of tungsten bronze material with excellent optical properties.
When tungsten bronze is not doped with Cs+, the tungsten bronze is yellow in color. And when the amount of Cs+ is increased to a certain extent, the color of the cesium tungsten bronze will be changed into blue. It is easier to disperse if the auxiliaries are added directly in the form of masterbatch, and therefore the use efficiency will be higher.
At present, thermal insulation masterbatch is widely used in the production of hollow sheets, which can be used in building curtain walls, hotels, and exhibition halls, etc. And it can be used in building film and automobile film, playing a role of heat insulation and energy saving. Also, it can be used in agriculture such as greenhouse films, thereby reducing internal temperature of sheds to promote photosynthesis.
