Violet tungsten oxide may be used to prepare thermal insulation paper with "high light transmission". This kind of heat insulation paper can almost completely block ultraviolet rays (99% UV blocking rate). The shielding rate of UV is not 100% as proper amount of ultraviolet radiation has a bactericidal effect and also has dings of adjusting and improving nerves, endocrine, digestion, circulation, respiration, blood, immune system, and promoting vitamin D production. However, excessive amount of ultraviolet light is not good, especially for the skin, eyes and immune system of the human body.
The heat-insulating paper of violet tungsten oxide nano powder has excellent heat insulation effect, so the temperature inside the vehicle is not too high, thereby reducing the operation degree of the air conditioner, and finally achieving the advantages of fuel saving and extending the life of air conditioner. While pursuing a good heat insulation effect, it is also necessary to consider the view in driving. If a heat insulating paper with low light transmittance is selected, the view is poor when driving at night. The light transmittance of the heat insulating paper of violet tungsten oxide is as high as 70%, so you do not worry about this problem.
