ng lasting, so it is very popular. Let 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. Application of photosensitive discoloration material: coating, suitable for various surface coating products, including PMMA spray paint, ABS spray paint, PVC spray paint. Ink, printing of various materials, including fabric, paper, synthetic film, glass, etc. Plastic products, suitable for various kinds of plastic PP, PVC, ABS, silicone rubber and other materials, such as the ejection, out of shape. waterproof-wristbands-for-eventsevent-wristbands-walmart ellent .
