Calcium chloride desiccants to absorb moisture | Absortech

Calcium Chloride desiccant absorbs more moisture when the relative humidity (RH) of the surrounding air is higher. At an RH of only 50%, calcium chloride’s moisture absorption is 150% its weight in water. And its absorption increases exponentially as Rh rises, which is a remarkable result compared to other desiccants, such as silica gel and clay.
