Calcium Chloride Desiccant |
High purity CaCl2 as its main absorption agent |
Chemical absorption, nontoxic and odorless; High moisture absorption ability |
up to 700% |
-5°C — 90°C |
Silica Gel |
SiO2 as the main ingredient, transparent and semi-transparent solid spheres |
Physical absorption with mild reaction; Chemically stable, relatively high mechanical strength; Granules with dry surface and no significant change in appearance after use; Reusable after oven drying. |
10% —27% |
below 35°C |
Clay |
Also called montmorillonite desiccant, in powder or ball form |
Additive-free, non-toxic, environmentally friendly |
15% —23% |
below 50°C |
Molecular Sieve |
Crystalline aluminosilicate with homogeneous aperture and relatively large surface areas and selectively absorption |
Recyclable, non-toxic, non-corrosive, chemically stable; Sensitive to environmental humidity, absorbs moisture even under ultralow humidity |
10% — 25% |
can be used at high temperature |
