Not all desiccants work the same way, and not every product requires the same level of moisture control. Selecting the right desiccant type and amount can make a big difference in performance, cost, and product safety.
Types of Desiccants:
1. Silica Gel: Ideal for electronics, pharmaceuticals, and food packaging. It’s non-toxic and reusable in some cases.
2. Clay Desiccant: Cost-effective for general use. Performs well in moderate humidity environments.
3. Calcium Chloride: High absorption capacity, perfect for ocean freight and containers exposed to extreme humidity.
Industry Applications:
1. Electronics & Semiconductors: Even small amounts of moisture can cause short circuits. Silica gel or molecular sieves are commonly used.
2. Machinery & Automotive Parts: Metals require desiccants with stronger water retention, such as calcium chloride bags.
3. Food & Pharmaceuticals: Use non-toxic, food-safe silica gel that complies with FDA standards.
4. Logistics & Warehousing: Large-scale desiccant poles or container strips keep cargo spaces dry for months.
Desiccant Sizing Choosing the correct size is just as important as type.
Factors include:
• Container or box volume
• Shipment duration
• Temperature and humidity conditions
