Silica gel is also called silicic acid gel. According to its properties and components, it can be divided into two categories: organic silica gel and inorganic silica gel. Organic silica gel is a highly active adsorption synthetic material and belongs to an amorphous substance. The main component of silica gel is silica, which is chemically stable and non-flammable. Moreover, the adsorption capacity of silica gel will decrease due to the adsorption of water vapor or other organic substances in the (medium) during use, so it can be regenerated and reused.

What is the function and use of silica gel? According to the molding process of silicone, it can be divided into injection molding silicone, liquid silicone products, special silicone products, and molded silicone products.

Injection molding silicone: Squeeze silicone through an injection machine to form in a mold, because silicone is thick and thick, and is often used to make some baby pacifiers, feeding bottles, mother and baby products, silicone toys, silicone gifts, etc.

Liquid silicone products: Silicone has fluidity and can be poured manually or by brush molding, or by machine injection molding. Condensed silica gel 100:2 is cured at room temperature (cured at 25°C for about 5-8 hours), and addition silica gel 1:1 can be cured at room temperature (cured at room temperature of 25°C for 3-4 hours), heating at 80-120°C 8-10 minutes to cure.

Special silicone products: This type of estimation is based on the chemical properties of silicone or the addition of some auxiliary raw materials. Special silicone products include high temperature resistant type, food grade (in line with US FDA standards), medical grade, flame retardant grade, etc. The silica gel can also have the characteristics of luminous, discoloration, negative ions, etc. by adding auxiliary raw materials.

Molded silicone products: Usually, solid silicone raw materials are used for secondary vulcanization in high temperature molds. Generally, the hardness of solid glue molding is 30-70°A. It is often used to make silicone accessories, buttons, silicone bracelets, silicone gifts, silicone kitchen utensils, silicone mats, silicone watches, mobile phone covers, etc.
