The Difference Between Organic Silica Gel and Inorganic Silica Gel

- Apr 29, 2020-

Organic silicone rubber is mainly divided into three categories, namely: silicone rubber, silicone resin and silicone oil, which mainly has the characteristics of temperature resistance, weather resistance, electrical insulation, physiological inertia, low surface tension and low surface energy.


Since silicone has these excellent properties, it has a wide range of applications. It can be used not only as a special material for aviation, cutting-edge technology and military technology departments, but also for various sectors of the national economy. Its scope of application has been expanded to: construction, electrical and electronic, textile, automotive, machinery, leather and paper, chemical light , Metal and paint, medicine and medical industries.

Inorganic silica gel is a highly active adsorption material, the main component is silica, is an amorphous machine made of sodium silicate and sulfuric acid in silica. The structure of inorganic silica gel is very much like a sponge. The interconnected small pores form a capillary pore adsorption system with a huge surface area, which can adsorb and store water vapor.

The selection range of inorganic silica gel for packaging materials is very wide, generally there are OPP / PE, PET / PE film, non-woven fabric, composite paper, etc. Used for gas drying, gas absorption, liquid dehydration, chromatographic analysis, etc. It is also used as a catalyst. If cobalt chloride is added, it will be blue when dry and red when it absorbs water.
