t by electric power. We call it glow in dark rubber band bracelets. Glow in dark rubber band bracelets is popular for nbottle opener keychainight event. A glow in dark rubber band bracelet can glow green or 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 for short wave visible light, sunlight and ultraviolet light (UV light) under 450 nanometers. Accept the ability. Here is the properties of the luminous powder. 1st short excitation time, long duration of luminous and afterglow, high brightness. 2ndvery stable physical and chemical properties, strong environmental adaptability, ordinary service life. 3rd safe and reliable, energy saving, green environmental protection.4th The particles are small, and the fineness and granularity are evenly distributed. In the actual life, people make use of the long time luminescence characteristics of night light powder to make a weak light source, and have special use in the military department. This material is applied to various kinds of switch signs on the aviation instrument, clocks, windows, machines, and the handle of the door, and can also be pressed into various symbols and parts together with a variety of transparent plastic materials. Supplies (such as power switches, sockets, fishing hooks, etc.). These light-emitting components are illuminated at night, at night or by accidental blackouts, and after lightning, and it still continues to glow, allowing people to discern the direction of the surrounding and bring convenience to work and life. The ultra-fine particles of luminous materials can be added to textiles to make thbottle opener keychaine colors more colorful. Children wearing luminous textiles can reduce traffic accidents. We use it to make the rubber band bracelet glow so as to contribute to night event. bracelet-montre-siliconerubber-band-bracelet-maker glow powder . The powder can be added into the band body or the ink for the printed or debossed infil style bracelet. The glow powder is eco as well as the silicone material bracelet. When absorbs enough strong light before being put in the dark, it glows blue, green or red depending on the style of the glow power. The glow will last for hours and gradually weaken.

Hope this can help you for the glow in dark silicone bracelets. A uv silicone bracelet can transfer its color darker under sunshine when absorbing uv light. It is not only with good looking appearance but also indicating the strength of the uv index. So some uv silicone bracelets made as the indication with the ruler of levels of index. Wearing on the wrist to avoid long time staying under strong uv. So what makes it uv transfer ? The answer is the UV phosphor which usd uv energy to open the sensitive molecular bond and make it jump from low energy to high energy level There will be a change from visible light to visible light, resulting in the changing color from light to dark. It become a uv silicone bracelet when the UV phosphor is put into the silicone mass and produce it a band.
