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 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 sblue wristbandsilica 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 rubberblue wristbands 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. A custom silicone is made from high quality silicone rubber with logo and message printed on. We can choose all the pantone for the wristband, no matter band or logo. The band can be solid, segment, swirl and logo can be debossed, embossed or printed. There is one kind call handwriting bracelet. There is an area that is writable on the surface. We can write ID, reminding message on it. So how can we make it ? There is a special silicone ink. It is writable. We can print a rectangle on the wristband. It is white like paper. We can write something on it. We can remove it and write again. So it is very useful for school, hospital or events. The ink is eco friendly also.
