Nano particle size tungsten trioxide for preparing window heat insulation film has excellent shielding performance to near-infrared rays of 800-1200nm. In other word, the nano grain size tungsten trioxide shows superior thermal insulation performance. The appearance of thermal insulation film of tungsten trioxide is a breakthrough revolution in heat insulation of glass and energy-saving industry as its thermal insulation performance is better than Low-e glass, insulating glass (hollow glass) and other heat insulating glass products.
The heat insulating glass made of nano tungsten trioxide powder has a visible light transmittance of 70%, an infrared shielding rate of 85%, and an ultraviolet shielding rate of 99%. Such thermal insulating glass also has the advantages of high heat insulation performance, high definition and low internal reflection. Also, it is energy saving, anti-glare and environmentally friendly without irritating odor. Moreover, it has stable performance and long service life. The most important point is that it will not shield signal, which is of great significance to phubbers.
