licone bracelet is a real green 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 bracelet 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 bracelet. The glow powder is eco as well as the silicone material bracelet.

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 tcustom wristbandshe 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 use 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. embossed-printed-wristbandmiscarriage-awareness-silicone-bracelets ere in all walks of life . But there will still be some defects in silica gel material properties . One of the defects of the silicone hand ring is that it can not be restored to its original state after deformation . What is the reason why the silicone bracelet can not be restored after deformation ? One of the reasons for the deformation of silicone bracelets is that the materials used in the production . custom rubber wristbands made of high quality silica gel are not only not easy to deform , but also have good elasticity and are not easy to break . And high quality silicone wristband are healthy and environmentally friendly , and it will not cause harm to human body .
