Blue tungsten oxide may be used to prepare blue-black heat insulation masterbatch, which may be used to develop products requiring high heat insulation, high infrared protection and high ultraviolet resistance such as films, sheets, and the like. And you may “see” such masterbatch in various kinds of films such as window films and films for agricultural greenhouses. And these thermal insulation films are environmentally friendly of high transparency.

It is reported that the anti-infrared thermal insulation masterbatch adding with blue tungsten oxide nano particles has the following characteristics: Safety and environmental protection without toxic and harmful substances. There is no fading and no attenuation of performance as the raw material is pure inorganic metal oxide with strong weather resistance. With good transparency and high definition, haze of such film is less than 1%. It also has the advantages of good dispersibility, good compatibility, and stable performance without precipitation. And it is uniformly distributed in plastics. Therefore, with the popularization of such heat insulating masterbatch, tungsten oxide is becoming more and more popular.
