Of course , just like the traditional Chinese medicine treatment in China . We can also use four methods to judge the quality of silicone bracelets: look, smell, ask and touch . 1.Look ( Appearance of rubber band bracelets ) Check if there are any dirty things inside the silicone bracelet , such as some color deviation , printing errors , whether the diameter of the bracelet is regular , whether the edge of the bracelet has surplus colloid . Generally, the edges and surfaces of high quality silicone hand rings are very smooth . 2.Smell ( The odor of rubber band bracelets ) Silicone bracelets are generally odorless. During the test, we can use fire to burn silica gel bracelets, high quality silica gel bracelets the residue after combustion is powder . The inferior silica gel bracelet has a bad smell after burning . 3.Ask ( Raw materials for rubber band bracelets ) We can ask the supplier whether silicone bracelet are made of pure silica gel . 4.Touch ( Touch the surface of silicone wristband ) The surface of high quality rubber band bracelets is very smooth and it"s very elastic . It will deformed and immediately restored as it’s tension and flexibility. Silicone 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. 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.

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 ibottle opener keychains 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 high quality so it is stretch bracelet. let’s see the feature of the stretch silicone plastic. Silicone plastic is the main component. There are many kinds of silicone plastic for different fields of industrial product. Silica gel contains organic silica gel and inorganic silica gel. Silicone plastic is one of organic silica gel. 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 wristband is named Polysiloxanes di-Me Me vinyl vinyl group-terminated chemically. We add curing agent to the soft original silicone plastic and mix them evenly, then put it to molding machine with high temperature of about 200℃, a few seconds later the silicone plastic gets solidified. Here comes the silicone wristband with custom logo by mould. Characteristic of the silicone plastic stay same on the process. All of our products are made from 100% high quality silicone plastic, eco-friendly, comfortable to wear and durable. pired. Now there are different size , different material and different logo stylle wristbands. What will the rubber bracelet be in the future? I think the most imagining is the material .
