. Let’s explain the what silicone rubber is and the its perfect characteristic. There are many types of silicone rubber for different fields of industrial product. Silica gel is a highly active adsorbent material, which belongs to amorphous material. Silica gel is a kind of amorphous silicon dioxide, mainly composed of silica. Its chemical property is stable, and it does not burn. Chemical formula is xSipromotion giftsO2?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 an 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. Characterispromotion giftstic of the silicone rubber stay same on the process but it get more strengthened. All of our products are made from 100% high quality silicone rubber, eco-friendly, comfortable to wear and durable.

They are changes from solid one by adding colors. Like the rainbow wristband, there are 7 solid colors segmented next each other. It is the inspiration from nature. It is a meaningful wristsband. The appearance of rainbow means the end of pain and suffering, the arrival of success and happiness. God will let them see the rainbow at the same time and receive God"s blessing. Legend has it that the person who expresses himself to you under the rainbow will be the most important person in your life. Aother one is swirled wristband. There are 2 to 4 colors on the wristband, swirled each other. The most inportant one is camouflage. It looks like a military uniform color. It is awesome you can wear it when you on the camp or outdoor. Looks handsome. This is the 2 kinds of fair wristbands, you can also make a mold-up on our ordering page to see how it looks better using different colors for the design.
