WO3 may be used to prepare a type of environmentally friendly thermal insulation masterbatch. The used WO3 powder is nano particle size tungsten trioxide, and the obtained masterbatch is a new inorganic nano-modified masterbatch, which not only has non-polluting property, but also has the characteristics of high transparency, high heat insulation and high UV resistance. In addition, the obtained nanoparticles have excellent uniformity, dispersibility and stability. And all these properties have reached a relatively advanced level so that the quality of the products made therefrom will not be reduced with higher heat insulation effect.

Usually, the masterbatch is prepared by a wet granulation process, that is, by dispersing a nano heat insulation slurry into a resin carrier. And these tungsten trioxide heat insulating masterbatch are widely used in transparent heat insulation films, transparent plastic sheets, transparent sunshade daily necessities, infrared anti-counterfeiting materials and other products that require high transparency and need to shield infrared rays.
