‌ Calcium chloride is an inorganic chemical compound composed of chlorine and calcium. It comes in flake, granular and powder form and has a strong hygroscopic property. Calcium chloride can be used as a desiccant.

The drying principle of calcium chloride desiccant is to use the hygroscopic property of calcium chloride. Calcium chloride can absorb moisture from the air and form hydrate calcium chloride. In this way, the relative humidity of the environment ‌is reduced.

Calcium chloride desiccant has strong moisture absorption ability. It can absorb moisture more than 300% of its own weight. It works rapidly to reduce the environment humidity.

Calcium chloride desiccant can be used for a wide range of applications, including clothing, furniture, bags, electronics, marine transportation and so on.

Calcium chloride gradually dissolves during the hygroscopic process, so it needs to be replaced regularly. 

Calcium chloride irritates the skin and eyes,  it is necessary to avoid direct contact when using and keep out of reach of children.
