more as a cosmetic surgery term than a material used in merchandise production. But silicone can come in many forms and grades. Some medical grade silicone is being used at your local hospital right now. That girl you just passed on the street... Something looked a little asymmetrical... What was it I wonder? Well, you get my point. Silicone is used in a lot of places. So what is the deal with the silicone used in the popular silicone wristbands? It"s a bonded polymer substance that possesses what the scientists (and very smart laymen) call "elastomeric qualities". These qualities lend the silicone various beneficial traits, such as being both resistant to water and a reasonable amount of heat. Prolonged exposure to the sun will make your silicone wristband sad, as this polymer does not like constant UV exposure. (If your head hurts, don"t worry. The hard part of this article is over. And if it makes you feel better, I almost passed out after writing that). You probably came here because you"re concerned that silicone may not be safe, right? Is this you: "I have kids. Is silicone safe for them to wear all the time? Is there anything toxic in it?" No, imaginary person! Silicone is a very common, safe product. It is free of lead and other harmful toxins. It"s also chemically inert, which means it will not react with other common chemicals your kids may find around your house. If it gets hot, it will not release any harmful fumes and if licked, it won"t transfer anything harmful to the quirky little licker. Silicone is not considered a hazardous waste. This unfortunately does not mean it"s biodegradable. The lifespan of this polymer is extremely long. But on the bright side? Silicone wristbands can be recycled after their lifetime as a fashion accessory has run its course. If you"re still thinking silicone might be too strange and exotic a material for your next merchandise endeavor, I"ll point out this: silicon is a naturally occurring element. It"s abundant in the sand and rocks outside your door. The silicone wristbands are made by the bonding of another pretty natural and accepted element: oxygen. The result may not seem all that natural, but it"s clear that it"s not dangerous and all studies show that it"s perfectly safe. rubber-wristbands glow green ofitness silicone wristbandsr blue after absorbing strong light energy under the effect of phosphor which is very small amount added and green to human. The glow will fade gradually in about 3h depending on how much light it absorbs. It is the best one for night event. Such music show, night walk and so on. The logo can be same as regular debossed, embossed or printed on the glowing wristbands. After exposure to natural light, fluorescent light, and ultraviolet light, the phosphor can store the light energy, stop the light and release it slowly in the way of fluorescence, so the light can still be seen at night or in the dark, lasting for hours to more than ten hours. The luminescent powder can be automatically lit in the dark. The main component is rare earth, which belongs to inorganic materials. The luminous powder first absorbs a variety of light and heat, converted into light energy storage, and then automatically luminescence in the dark, by absorbing all kinds of visible light to realize luminescence. The product does not contain radioactive elements, and can be used indefinitely, especially fofitness silicone wristbandsr short wave visible light, sunlight and ultraviolet light (UV light) under 450 nanometers. Accept the ability. A UV rubber 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.
