Absorbs more than 300% of its own weight — the workhorse for container and warehouse protection.

Calcium chloride desiccant is a widely used moisture-absorbing material that adsorbs humidity from the air to reduce moisture. It has strong hydrophilicity: when exposed to humid air it absorbs surrounding moisture through a hygroscopic reaction. Its structure contains hydrates that form compounds with environmental moisture, thereby adsorbing water. It has a high moisture absorption capacity and continues to absorb humidity until saturation.
