- More than 10x the moisture absorption power of traditional desiccants.
- Rapid moisture uptake ensures long-lasting dryness.
Visual moisture indication
- Powder turns into gel as moisture is absorbed.
- Easily identify saturation level - no guesswork required.
Leak-proof design
- Inner layer: one side Tyvek® Paper/Dulai Paper, one side transparent OPP film.
- Outer layer: customizable breathable non-woven fabric.
- Gel formation locks in moisture - no liquid leakage or re-release.
Safe and eco-friendly
- Non-toxic, odorless, and corrosion-free.
- Complies with REACH, RoHS, and other international safety standards.
How Does It Work?
- Place the desiccant inside packaging, containers, or enclosed spaces.
- The powder absorbs moisture and transforms into a solidified gel.
- Once the desiccant feels hard or gelled, it has reached full absorption and should be replaced.
The gel remains stable and sealed - no leakage, no mess.

Applications
1. Refrigeration Brine / Cooling Agent
Calcium chloride solutions can remain liquid at temperatures as low as -50°C, making it an excellent brine for industrial refrigeration and cold storage systems.
2. Desiccant / Moisture Absorber
As a powerful hygroscopic compound, calcium chloride is widely used as the main component in desiccants for moisture control in packaging, electronics, containers, and more.
3. De-icing and Snow Melting Agent
Commonly used on roads, parking lots, and sidewalks in snow-prone areas. Calcium chloride quickly melts ice, even at low temperatures, and prevents re-freezing.
4. Dehydrating Agent in Chemical Industry
Used in the production of alcohols, esters, ethers, and acrylic resins, where calcium chloride acts as a reliable dehydrating agent.
5. Refining Agent in Metallurgy
In aluminum and magnesium smelting, calcium chloride serves as a refining agent, improving metal purity and efficiency.
6. Fire Retardant for Textiles
Calcium chloride can be applied as a fireproofing agent in fabric treatment, enhancing flame resistance.
7. Dust Control Agent
Applied to unpaved roads and construction sites, calcium chloride binds dust particles, reducing airborne particles and erosion.
8. Concrete Accelerator and Anti-freeze Additive
Used in construction to accelerate cement hydration, improve early strength of concrete, and enhance freeze-resistance in cold weather.
