Nanometer yellow tungsten oxide may be applied for preparing thermal insulation paper, which has excellent infrared blocking rate, UV blocking rate and good visible light transmittance. In other words, yellow tungsten oxide nanopowder can fully meet the data that needs to be paid attention to when selecting heat insulation paper - The degree of light transmittance, the degree of infrared ray isolation (infrared blocking rate/IR shielding rate), the degree of ultraviolet ray isolation (UV blocking rate/UV shielding rate) in the specification sheet. There is something about the degree of light transmittance below.
As the name suggests, the degree of light transmittance is the extent to which visible light penetrates the heat-insulating paper. Due to its own high transparency, this kind of heat-insulating paper has the same heat insulation effect even if the value of light transmittance is quite high. Unlike other thermal-insulating paper, the higher the light transmittance is, the hotter the space it is. So, there is no need to worry about the problem --- the lower the transparency of the heat-insulation paper is, the darker the heat-insulation paper is. Besides, it does not affect your view at night driving.
