WO3, mainly tungsten trioxide nano particles, may be used to produce thermal insulation dispersion. And the prepared tungsten trioxide nano dispersion is a heat insulating medium for building window film with high transparency and high heat insulation performance. In addition, the environmentally friendly thermal insulating dispersion has the characteristics of excellent stability, compatibility, dispersibility and weather resistance.

The heat insulating nano dispersion of nano particle size tungsten trioxide has a good absorption and reflection effect on ultraviolet rays and near-infrared rays. In particular, the yellow dispersion has a higher shielding capability to near-infrared rays in the near-infrared region than ATO and ITO dispersions. And such new heat insulation dispersion can be used in a variety of transparent UV resins or other transparent resins in a variety of systems to produce a variety of highly transparent window films or transparent thermal insulation coatings of high heat insulation.
