Nanometer yellow tungsten oxide may be used in the preparation of nano-ceramic color master, in which the solid content of yellow tungsten oxide nanopowder is between 5% and 10%, the infrared blocking rate is between 60% and 99% (changing with the addition ratio), and the visible light transmission ratio is between 70% and 80%. Besides, the finished product has a haze of less than 1. In addition, the weather resistance is good. Therefore, this type of color master is widely used in transparent heat-insulating films, transparent sunshade daily necessities, infrared anti-counterfeiting materials, transparent plastic sheets and other products requiring high transparency and high shielding rate of infrared rays.
Such nano-ceramic masterbatch revolutionizes the application of inorganic yellow tungsten oxide material of high heat insulation performance in the field of highly transparent plastics/films, resulting in clear and transparent final products with high shielding rate to infrared rays and extremely low haze.
