The exceptional moisture absorption of our Magnesium Chloride Desiccant stems from its core ingredient: high-purity Magnesium Chloride. Sourced directly from nature, this high-purity compound is obtained by evaporating and concentrating seawater, salt lake brines, or bittern left over from salt production, followed by a refining process. Unlike many synthetically produced chemical agents, this natural origin from the ocean and salt lakes gives it an inherent environmental affinity.
Our Magnesium Chloride Desiccant is a highly efficient moisture-absorbing product crafted from this high-purity base. It works through strong chemical absorption, actively and aggressively capturing water molecules from the surrounding environment and binding them through a stable hydration reaction. This mechanism ensures powerful and consistent moisture uptake across a wide range of humidity levels, offering a far greater absorption capacity than standard physical adsorption desiccants.
A key innovation lies in our proprietary formula and manufacturing process, which effectively overcomes the potential challenge of moisture release (“regurgitation”) common in highly absorbent chlorides. The product rapidly transforms and securely locks absorbed moisture within its matrix, preventing any risk of liquid seepage after saturation. This combination of high efficiency and reliable safety makes our Magnesium Chloride Desiccant a trusted choice for demanding moisture protection applications.
What are the advantages of Magnesium Chloride Desiccant? There is no single “best” desiccant type, as each has its own strengths, ideal applications, and limitations.
Compared to traditional clay and silica gel desiccants, Magnesium Chloride Desiccant offers a superior moisture absorption rate and a wider effective temperature range. This makes it particularly effective for demanding scenarios involving high moisture volumes or harsh conditions, such as preventing “container rain” during sea freight or providing long-term protection in large storage spaces. Its high-capacity, sustained absorption delivers stronger security.
This creates a complementary system of moisture solutions for diverse needs: the efficiency of Magnesium Chloride for tough jobs; the stable, non-corrosive nature of Silica Gel for sensitive electronics; its food/product contact safety; and the widespread use of Clay Desiccants where basic, cost-effective protection suffices.
Performance Comparison (Typical Values):
- Magnesium Chloride Desiccant: Absorption Rate ≥ 400%, Temp. Range: -35°C to 95°C
- Clay/Calcium Chloride Blend: Absorption Rate ≤ 85%, Temp. Range: < 50°C
- Clay Desiccant / Silica Gel: Absorption Rate: ≤ 30%, Temp. Range: < 50°C (Clay) / < 37°C (Silica Gel)
Our Magnesium Chloride Desiccant is formulated with magnesium chloride and a polymer adsorption material. It works by aggressively trapping ambient moisture, gradually hardening into a solid block upon absorption. This transformation effectively locks in the moisture, preventing any reverse seepage and ensuring a leak-proof performance.
Before Absorption
Absorbing Moisture
After Absorption
The high moisture absorption of magnesium chloride demands robust packaging. Our desiccant utilizes Tyvek, a material known for its excellent breathability, durability, and superior leak prevention. A transparent film on the reverse side allows for easy visual inspection of saturation levels. A traditional two-layer packaging option is also available; please contact us for details.
Traditional Two-Layer Packaging:
Tyvek Packaging:
Tyvek Front: Breathable, strong, and leak-proof.
Transparent Film Back: For clear saturation monitoring.
Full-Back Adhesive (Peel-and-Stick Version): Optional for secure placement.
Our magnesium chloride desiccant offers flexible application methods to suit various protection needs—it can be adhered, placed, or hung as required. Contact our team to determine the optimal solution for your specific application.
Adhesive-backed for secure placement on surfaces
Easy placement in enclosed spaces
Hangable for vertical or overhead protection
