bsorbing 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 tenpromotion gifts 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. 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.  

Silicone products can be divided into three categories according to the different molding process. Molded silicone products are usually made by being put into the high temperature mold after the addition of curing agent in the solid silica gel through the curing machine pressure and high temperature into a solid. 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. So as for silicone bracelets. Extruded silicone products are usually extruded through the extrusion of silicone molding. The general shape of the extruded silicone long and tubular which can be cut, but the shape of the extruded silicone has limitations. Liquid silicone products are made through the injection molding of silica gel. Because of its soft characteristic, widely used in the simulation of human organs.  

ccording to customer’s request for free. 2 make the mould The mould is made by the artwork that is confirmed by customer. A mould is made from copper usually. It is a necessary step to start production. 3 Color and rubber mixing This is the step to prepare the raw material of the bracelet.  We have to make the color as the pantone color customer wants. 4 weighing Commonly 5.5g per bracelet. 5 start production Set the mould on the machine and warm up to needed tempreture. 15k pcs bracelets can be done in 1 day by 1 machine. 6 edge cutting Use the machine to cut the extra part of the bracelet and divice the bands made by one mould. 7 quality inspecpromotion giftstion The defective must be picked out before packing. 8 packing and dilivery The bulk packing is 100pcs/ bag, 2500pcs/ctn. There can be individually wrapped if customer request. We have the confirm the dilivery details before dispatching.
