reen jewelry with wear-resistant , high temperature resistance, no deformation and no side effects on body. Silicone bracelet has certain care function while some functional materials such as negative ions added into the bracelets A glow in dark silicone wristband is made by the same technology with the normal bracelet but adding the glow powder . The powder can be added into the band body or the ink for the printed or debossed colorfilled style wristband. 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. But when reabsorbs the light , it globeer bottle openerws again like original shows. It is the most favorable item for the night event. It looks so good in the dark reflecting the logo custom. Hope this can help you for the glow in dark silicone bracelets. A uv silicone wristband 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. there are also some inferior or counterfeit silicone products.So how do we judge the quality of silicone products when we buy silicone products? First, wear resistance Wear resistance is formed after the production of athletic silicone products. The surface of silicone products can resist loss. Good athletic silicone products generally have little surface friction because of external factors, do not affect the appearance of performance, text, color. However, the surface characters of inferior quality silicone products are easy to fall off. Second. Tear strength and tensile strength Athletic silicone products with high tear strength have outstanding anti destructive ability,Long life,not easily affected by external environment. Poor tearing strength of silicone products is generally manifested in the tearing process prone to cracks, thus rapidly expanding the cracking and causing damage. Third, hardness and tensile stress An important beer bottle openerindicator of the rigidity (stiffness) of the rubber material. Hardness and elongation stress are the forces needed to produce certain deformation of silicone products.So when buying silicone products, the most important thing is to look at the wear resistance, elasticity and tear strength first. If it meets the requirements, it is a good quality silicone product. If it is not satisfied, give up, so as not to cause financial loss. Fourth. Elasticity Athletic silicone products have good elasticity because high elasticity mainly comes from the movement of molecular segments of silicone.So when buying silicone products, look at the elasticity of silicone products to judge the quality. Fifth. Fatigue resistance When the silicone product is subjected to alternating stress (or strain), the change in the structure and properties of the material is called fatigue. The fatigue damage is caused by fatigue failure as the fatigue process proceeds. camo-silicone-wristbands24-hour-silicone-wristbands m silicone wristband run a factory in China. Preferential policies and low labor cost is the main reason. A Chinese silicone wristband producing factory usually make the wristband from silicone but not producing silicone. They purchase raw material from all over the world so that make the silicone wristband low price. So Make In China is cheap and of high quatity as well. Guanddong and Zhejiang province is the two place famous for custom silicone wristband. Near 200 silicone wristband making factory located in Guanddong province. They provide tons of wristbands every day of all kinds like debossed, embossed and printed wristband. Silk screen printing is applied for printed silicone bracelets. Modern screen printing technology is making screen by photoengraving method using photosensitive material ,oil paintings, prints, posters, name card, binding covers, packaging, commodity, textile printing and dyeing, glass and metal plane carrier. And also this is the printing method for the printed silicone bracelets.
