SORBSTAR Montmorillonite clay packets is a chemically inert, non-corrosive and reusable desiccant. It works by adsorbing and trapping moisture from the air, lowering humidity and preventing the formation of mould, condensation & rust in enclosed spaces.
SORBSTAR montmorillonite packets can adsorb up to 18%-20% of their weight in water vapour at 25°C and 80% relative humidity.
At full moisture capacity, montmorillonite remains dry with no change in size or shape.
100% natural clay, non-toxic, biodegradable, and safe for the environment.
Performs well under moderate humidity, maintaining consistent protection.
Suitable for electronics, food, pharmaceuticals, textiles, logistics, and general packaging.
More economical compared to silica gel while still providing reliable desiccant performance.
Can be reactivated by heating at 110–120°C for repeated use.

Applications
Both Montmorillonite Desiccant and Mineral Desiccant are widely used solutions for moisture control, but they are not exactly the same. Mineral desiccant refers to a broad category made from different natural minerals, while Montmorillonite desiccant is a specific type derived from bentonite rich in montmorillonite clay. To help you understand the key differences and choose the right option for your products, here is a clear side-by-side comparison.
| Category | Montmorillonite Desiccant | Mineral Desiccant |
|---|---|---|
| Definition | A specific type of natural mineral desiccant made from bentonite rich in montmorillonite. | A general category of desiccants made from various natural minerals such as bentonite, zeolite, or attapulgite. |
| Moisture Absorption | Strong and stable, especially effective under low humidity conditions. | Moderate, performance depends on the type of mineral used. |
| Moisture Retention | Holds absorbed moisture firmly, less likely to release back. | May release some moisture under certain conditions. |
| Appearance | Light gray to pale yellow granules, minimal volume change after absorption. | Gray-white or light brown granules, may expand slightly after absorption. |
| Environmental Impact | 100% natural, biodegradable, non-toxic, safe for sensitive applications. | Natural and eco-friendly, but quality varies with mineral source. |
| Typical Applications | Pharmaceuticals, military equipment, optical instruments, precision electronics. | General packaging protection: shoes, textiles, furniture, food, electronics. |
All Montmorillonite Desiccants are Mineral Desiccants, but Montmorillonite offers superior moisture absorption, stability, and reliability, making it the premium choice for sensitive and high-value applications.
