Tungsten oxide may be applied to automotive glass in the form of heat-insulating film or heat-insulating coating, and finally car thermal insulation glass with good heat insulation and heat preservation performance may be prepared. As we all know, automotive glass has the front windshield, rear windshield and the side windshield.

Among them, the front windshield put higher requirements on the raw material. According to the traffic safety regulations of the Ministry of Public Security, the light transmittance of the front windshield must be greater than 70%, so as not to affect the safety of driving. In other words, whether it is a thermal insulation film or a thermal insulation coating, the light transmittance of the front windshield must be greater than 70%. There are data showing that the tungsten oxide film and the thermal insulation coating have a light transmittance higher than 70%. And the heat insulation effect of such two heat insulation materials is good. Also, they shield the ultraviolet rays, thereby protecting the center console components from long-term sun irradiation.
