e 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 k if made color filled or printed. So what is silicone and what the characteristic of this ink. Silicone also named silicone rubber which is a kind of high activity adsorption material with non-toxic, tasteless, stable chemical properties and have higher mechanical strength. The silicone wristband is comfortable to wear and long lasting with the characteristic of silicone rubber. Silicone wristband is a kind of molded silicone product. Molded custom keychain tagssilicone products are usually put through the high temperature mold in the addition of curing agent after the solid silica gel through the curing machine to put pressure into solid molding. The shape of the mold determines the shape of the molded silicone products. Molded silicone products is currently the most widely used in the silicone industry. The silicone ink is a coatingcustom keychain tags protection ink used on silica gel material which is environmentally friendly , non-toxic and harmless.
