Color Change Silica Gel Desiccant
Silica Gel is a high-activity absorbent which is the result usually through chemical reacting between Sodium Silicate and sulfuric acid and aging, sour bathing and over physical process. It has a stable chemical property and never reacts with any substance except the alkali and hydrofluoric acid. It is widely used to controlling humidity and preventing dampness of products.
| Ingredient | Content (%) | Ingredient | Content (%) |
| SiO2 | 99.6 | Na2O | 0.17 |
| Fe2O3 | 0.02 | MgO | 0.01 |
| CaO | 0.04 | Al2O3 | 0.16 |
Silia gel has the feature of high absorption capacity, good thermal stability, high mechanical strength, non-toxic, odorless and environmental friendly. It is the only desiccant that can contact with the food and pharmaceuticals.
