mical 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,rubber band bracelets 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. Characteristic of the silicone rubber stay same on the process but it get more strengthened. custom-wrist-sweatbandssiliconeband-ca proteins, cells or other particles that, when present in the blood, can affect the health or health of users. Our store can not make the bracelets that destroy cancer physiologically, but we can customize one that can inspire people to fight against cancer mentally. As we all know, cancer is a horrible disease. People who suffer from cancer must keep good mood and be encouraged, or it will be a hard battle. A custom rubber bracelet can help. We can make a slogan like beat carcer, fuck carcer on the bracelet. We can make the size of bracelet, color of the bracelet and logo, logo style different. The size is 150mm, 180mm and 202mm or otherubber band braceletsr customized size. We can use all pantone colors for the wristband and logo.
