In the past few years, experts began to conduct special research on the optical properties of Cs0.32WO3 nanoparticles (cesium tungsten bronze nanoparticles). Later, they found that cesium tungsten bronze particles may be used as a new type of heat-insulating dingal particles for the production of transparent thermal insulation paper for applying in automotive glass. The “paper” is transparent heat insulation car film.

Experts said that the heat insulation film of cesium tungsten bronze nano dingal particles has a greatly improved infrared shielding capability, which is conducive to creating a more comfortable, environmentally-friendly and energy-saving interior environment. In other words, such film can greatly improve the comfort of human body and greatly save energy. At the same time, it has an extremely long service life. This is mainly because nano cesium tungsten bronze has a significant improvement in the infrared blocking ability of 800-1200nm, which can block infrared rays by 80-90% and ultraviolet rays by more than 99%. Also, it has visible light transmittance of more than 70%. At present, the heat insulating nanoparticles of cesium tungsten bronze has been widely recognized by many glass giants. And it has also been used in the production of coated insulating glass.
