Yellow tungsten oxide powder is the raw material for preparing a transparent heat-insulating film. And the obtained smart film can be applied to building glass or automotive glass to obtain a transparent heat insulation glass. According to experts, it is a UV-resistant film with a UV shielding rate of over 99%. Be aware that long waves in ultraviolet light can penetrate glass, even 9 feet of water. It can be seen that the raw material tungsten trioxide nanoparticles have super ultraviolet shielding ability.

Experiments have shown that a room of 13 square meter, air conditioning power consumption per month is 80kw/h. After the room is attached with a transparent heat insulation film of tungsten trioxide nanoparticles, the monthly air conditioning power consumption is reduced to 56kw/h. The indoor temperature can be effectively reduced by 3°C-7°C, saving 30% of air conditioning electricity. Certainly, such thermal insulation film can also help you block the annoying glare, allowing you to bathe directly in the sun without being hurt by the harsh sunlight.
