Cesium tungsten oxide can be applied for preparing thermal insulation film, making it safer, more durable and heat-insulating.
The thermal insulation film containing cesium tungsten oxide has good physical properties such as water resistance, weather resistance, anti-aging, and no communication interference, as well as nice optical properties such as high blocking rate on infrared rays and UV with high transparency. In a word, it solves the problems of the structural complexity, stability, and durability of the same type of thermal insulation film.
This type of thermal insulation film has ideal optical properties. At room temperature, the ultraviolet ray transmittance of this film is 0.3%, the near-infrared ray transmittance is 7.0%, and the visible light transmittance is 72.6%. The reason why thermal insulation film is important is that the ultraviolet rays can directly penetrate skin, resulting in the appearance of melanin, thus promoting skin aging. What is worse, long-term exposure to ultraviolet rays can increase the risk of skin cancer.
