Calcium Chloride
1. Product Introduction
Calcium chloride is a white color, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous. As calcium chloride has properties of quick dissolving, exothermic ability, it absorbs moisture from the air and surroundings, dissolves at very low temperature.It is widely used in snow and ice melting, dust control, moisture-absorbing, concrete acceleration, brine refrigeration systems and additive to oil well completion fluids.

In mixing with modified starch or carboxymethyl cellulose, calcium chloride may make a powerful desiccant, which can absorb 250% of its own weight, at the same time, the modified starch or carboxymethyl cellulose may take the salt water to form a jelly. We pack 50 gram - 200 gram calcium chloride desiccant bags. Moreover, we may work several calcium chloride bags to a long chain calcium chloride desiccant with hook, which is good to use in the ocean container transportation.
We are supplying quality calcium chloride, modified starch and carboxymethyl cellulose in bulk and are working with the final calcium chloride based desiccant upon customer’s specific requirement.
