uler 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 vfree wristbands samples ukisible 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. Different color of the bracelet has different meanings. Band color white stand for making poverty history. Yellow stand for livestrong. Black and white stand for standing up and speaking up. Blue stand for beatting bullying. Pink stand for supporting knowledge strength. Blue and white stand for one world one cause Blue and green stand for say no to sectarianism. Also a silicone bracelet can be used as a promotional item for entertainment or sport. It is hot sale as a advertisement gift.  

licone bracelets , What do we need to pay attention to ? 1.Smell the scent of silicone bracelets . We can use fire to burn silicone bracelets . When we burn the high quality silicone wristband , the edge of it is white and the residue after combustion is white powder . The inferior silicone bracelet has a black edge and a foul odor after burning . 2.Check the color of the silicone rubber bracelet . All manufacturers produce silicone bracelets in the same color as Pantone color card . So if we find the color of the wristband is different from the pantone color card , the quality of the rubber bracelet is not ok . And Check whether the surface and edge of the silicone bracelet are smooth . 3.Check the logo . If we choose to printed the logo on the wristband , We need to check that the logo on the silicone bracelet is clear .   In addition to paying attention to the quality of the silicone bracelet itself , We also need to focus on suppliers . We need to pay attention to whether suppliers have environmental testing reports and whether the company"s environment is good . All of these can provide guarantee for us to customize high quality silicone bracelet .    

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.  

Its chemical property is stable, and it does not burn. Chemical formula is xSiO2?yH2O. Silica gel contains organic silica gel and inorganic silica gel. Inorganic silica gel is a highly active adsorption material. It is usually prepared by reaction of sodium silicate and sulfuric acid, and a series of post-processing processes such as aging and acid bubble. Household use desiccant, humidity regulator, deodorizer belongs to inorganic silica gel.Organic silica gel is anfree wristbands samples uk organosilicon compound. It refers to a compound containing Si-C bond and at least one organic group, which is directly linked to silicon atoms. It is mainly divided into four categories: silicone rubber, silicone resin, silicone oil and silane coupling agent. There are 4 types of silicone products, moulded silicone products, extruded silica gel products, liquid silica gel products and special silicone products. Silicone rubber is one of organic silica gel and it is one of the moulded silicone products Temperature resistance, weatherability, electrical insulation performance, Physiological inertia, Low surface tension and low surface energy are the outstanding characteristics of organic silica gel. The one we use to make bracelet is named polysiloxanes di-Me Me vinyl vinyl group-terminated chemically. We add curing agent to the soft original silicone rubber and mix them evenly, then put it to molding machine with high temperature of about 200℃, a few seconds later the silicone rubber gets solidified. Here comes the silicone bracelet with custom logo by mould. Characteristic of the silicone rubber stay same on the process but it get more strengthened.
