me talk something about UV silicone wristband. A UV silicone bracelet can transfer it’s color darker under sunshine when absorbing UV light. It transfer to purple or blue normally which indicating the strength of the UV index. Wearing it on the wrist is a good way to avoid long time staying under strong sunshine. We add UV powder which is also green as silicone in production. The UV powder is kind of photochromic material. We use it to make this change. Photoreceptor color is irradiated by ultraviolet or sunlight, absorbs ultraviolet or sunlight, and produces changes in color. When it loses ultraviolet or sunlight, it returns to the original color. Photoreceptor products, after sunlight or ultraviolet radiation, can absorb the energy of the sun or ultraviolet rays, produce changes in the molecular structure, lead to changes in the absorption wavelength, and produce color changes; when the sun or ultraviolet energy is lost, the original molecular structure is restored and the color of the cost is reduced.
