This type uses calcium chloride as the main absorbent and modified starch as the coagulant. Calcium chloride can deliquescence in the air and absorb a large amount of water, thereby forming crystals. Modified starch absorbs calcium chloride crystal water to form a gel, which makes our CA type desiccant safe and leak-free after absorption. And, we'll use waterproof, moisture-permeable double-packs to make the desiccant safer.
