Calcium Chloride Anhydrous Lumps (90%)
White anhydrous lumps · CAS 10043-52-4
Also see our standard Calcium Chloride Granules (94% Purity, Industrial Grade) page.
Overview
Calcium Chloride Anhydrous Lumps (90%) sit in the middle of our calcium chloride range: stronger than the 75% fused lumps, but still in lump form rather than the 94% anhydrous powder. With at least 90% CaCl₂ and very little bound water, the lumps pull in a lot of moisture per kilo, which is why buyers use them for drying gases, solvents and used oils, as well as for oil-field brines and de-icing. Lumps are easy to load into dryer beds and absorbent bags. Suraj Chemicals supplies them from Chennai across India.
