Nano cesium doped tungsten oxide may be applied for preparing thermal insulation masterbatch. The new environmentally-friendly masterbatch has multiple characteristics such as high transparency, high heat insulation, high energy efficiency, and environmental protection. And it can be used to produce heat insulation PC sheets or heat insulating films of different thicknesses.
The architectural window using such sheet or film can achieve the effect of "warm in winter and cool in summer". If such a heat insulating film or sheet is applied to a greenhouse, the production and income can be increased, and the power consumption can be reduced. If it is applied to a car canopy, it can also block the amount of heat from the car, reduce the temperature inside the car, and reduce the energy consumption of the car air conditioner.

According to experts, the masterbatch of cesium doped tungsten oxide nano particles has excellent spectral selectivity and stability. The visible light transmittance is over 80%, and the near-infrared blocking rate is over 90%. That is to say, the heat insulating effect of such material is remarkable, blocking the near-infrared rays carrying heat in the light wave radiation, and the overall infrared shielding rate is as high as 90% or more, which can save energy consumption by 20-30%.
