Chunwang Bentonite Desiccant (also known as Montmorillonite Desiccant) is sourced from abundant natural mineral deposits. Our commitment to sustainability guides its extraction and processing, adhering to strict environmental standards that prioritize ecological protection and site rehabilitation.
The manufacturing process involves primarily physical methods—including ore beneficiation, organic matter carbonization, bentonite expansion, steam treatment, drying, activation, crushing, and screening. It requires no strong chemical reagents and consumes relatively low energy, reflecting our responsible use of natural resources.
Through physical modification, the bentonite acquires excellent moisture absorption properties. At end of life, the product biodegrades naturally or can be safely repurposed—such as for soil conditioning—leaving virtually no harmful residues, offering an eco-friendly drying solution.
It complies with U.S. Military Standard MIL-D-3464E and Chinese Military Standard GJB2714-96.
Key Features:
- Low moisture content in raw material
- Non-corrosive and safe, even in direct contact with metals
- Rapid adsorption and high capacity owing to its natural mineral origin
- Non-toxic, non-corrosive, environmentally friendly, and 100% biodegradable
- High bulk density (>980 g/L), offering high volumetric adsorption with less space required per weight
- Neutral pH (7.0 ± 0.5) and effective even in low-humidity environments, ideal for metals and sensitive applications like electronics, instruments, and hardware
- Cost-effective performance

How to Select Packaging Materials for Desiccants?

Tyvek Packaging
This material offers one-way breathability and is highly resistant to tearing and aging. It remains lint-free and can withstand exposure to acids and alkalis.

SMS Non-Woven Packaging
Known for its good breathability and high toughness, it provides a cost-efficient packaging solution.

Kraft Paper Packaging
Produced without bleaching agents, it features a plastic-free heat seal and is fully biodegradable.
It is widely used in a broad range of products and industries, including packaging, precision instruments, semiconductors, metal products, electronic components, aerospace, military supplies, textiles, steel cords, copper and aluminum foils, scanners, air compressors, and medical equipment.
