What material is silicone
Silica gel is a highly active adsorbent material, which is an amorphous material. Except for strong alkali and hydrofluoric acid, silica gel does not react with any substance, nor is it soluble in water or any solvent, it is non-toxic and tasteless, and its chemical properties are stable. Various types of silica gel form different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength.

What are the uses of silica gel:

1. Silica gel can be divided into macroporous silica gel, coarse-pored silica gel, B-type silica gel, and fine-pored silica gel according to the size of its pore size. Different sizes of pores lead to different adsorption capacities. Coarse-pored silica gel has higher adsorption capacity in the case of high humidity, fine-pored silica gel has a higher adsorption capacity than coarse-pored silica gel in the case of low relative humidity, and the adsorption capacity of B-type silica gel is between coarse and fine pores. . Macroporous silica gel is generally used as catalyst carrier, matting agent, toothpaste abrasive, etc.

2. The use of silica gel has the characteristics of strong adsorption, can quickly and effectively absorb the moisture in the sealed package, stable chemical properties, non-toxic and harmless. In recent years, various silica gels have been widely used in drug purification, DNA separation, food drying, high-precision electronics, advanced cosmetics, sewage purification, beer purification, advanced coatings, and resin production or preservation.
