2 g opp bag white plastic desiccant

Silica gel desiccant is a highly active adsorption material, usually is to use sodium silicate and sulfuric acid reaction, and after aging, acid soak and a series of process and system.
Silica gel is amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and any solvents, non-toxic, tasteless, stable chemical properties, in addition to the strong alkali, hydrofluoric acid does not react with any material.
Chemical components and physical structure of silica gel, determines it has many other features of similar materials difficult to replace.
High silica gel desiccant adsorption performance, good thermal stability, chemical stability, high mechanical strength.
