Choose The Right Desiccants for Your Goods

Calcium Chloride Desiccants and Magnesium Chloride Desiccants: Which One is Better for You?

CALCIUM CHLORIDE DESICCANTS
Calcium chloride (CaCl2) is a type of salt that can absorb up to 10 times its net weight in water to form a hydrate, which is also known as salt brine. Most Calcium chloride desiccants are a mixture of anhydrous CaCl2 with starch. They absorb moisture and transform it into a gel. Calcium chloride desiccants are highly effective and can absorb moisture for up to 90 days. They can absorb up to 300% of their dry weight, making them the perfect solution to protect cargo from moisture damage during long-haul ocean shipments.

MAGNESIUM CHLORIDE DESICCANTS
Magnesium chloride (MgCl2) is a type of salt that can absorb water and form a hydrate (salt brine) that can weigh up to six times its weight. There are dry-dry type desiccants available that use the chemically changed anhydrous MgCl2 to absorb moisture without turning into a liquid. As it absorbs moisture, it turns into dry lumps without any liquid stage. Magnesium chloride desiccants are similar to Calcium chloride desiccants, but they have a lower absorption capacity of up to 200% of their net weight and an effective application time of up to 60 days. Magnesium chloride desiccants are a suitable alternative to Calcium chloride desiccants for use in ocean transport conditions. They are a good choice for users who don’t want the gel stage of Calcium chloride desiccants, despite being more expensive.

In conclusion, both Calcium Chloride and Magnesium Chloride desiccants play crucial roles in protecting cargo from moisture during ocean shipments. While Calcium Chloride desiccants, like Super Dry, offer an impressive absorption capacity of up to 300% of their dry weight, providing a reliable solution for extended journeys lasting up to 90 days, Magnesium Chloride desiccants offer a viable alternative. Furthermore, the Calcium Chloride formula turns moisture into a gel, captured and contained inside a packet, isolated and leakage-free, eliminating the release of moisture. In comparison, other types of desiccants have a higher risk of releasing moisture when they reach their maximum absorption.

For superior moisture protection during long-haul ocean shipments, Super Dry’s Calcium Chloride desiccants stand out as a trusted and effective solution. Explore our moisture prevention solutions at www.superdryers.com and safeguard your cargo with the best in the industry.
