Nano cesium tungsten oxide may be used as a thermal insulation film in heat insulating window glass. So, the window glass will has the following advantages:
1. Anti-glare, so that drivers have a clear vision, to ensure the safety of driving;
2. Shield 90% of the UV, to prevent in-car items such as plastic parts and rubber parts from fading and even aging;
3. Protect people from secondary damage of broken glasses.
Nano cesium tungsten oxide heat insulating film used in window glass is mainly based on the principle of photochromism, which make the film change color in the light, from colorless to blue or other colors (In terms of car film adding other ingredients), so that it has a good shielding effect to ultraviolet light. In addition, this material is environmentally friendly with reliability so that it may not pollute ecological environment, which overcomes the solid waste pollution produced by using other heat insulating materials. Compared with other car films, this type of heat insulation film has the advantages of no pollution, easy operation, high efficiency and no corrosion of workpieces.
