Calcium chloride lumps are fused calcium chloride in solid lump form. They absorb moisture strongly and slowly turn to brine, which makes them practical for humidity control and dust suppression.
This 75% grade is used for moisture absorption, dust control and road stabilisation, water treatment, oil and gas applications and de-icing.
