Frequently Asked Questions
What is the difference between a desiccant and an adsorbent?
A desiccant is any substance that removes moisture to keep its surroundings dry, while an adsorbent does so by bonding water to its surface.
Adsorbents such as silica gel and molecular sieves are therefore a specific category within the wider desiccant family.
Which desiccant is best for long ocean shipments?
Calcium chloride desiccants are widely used for ocean freight because they absorb large amounts of moisture over long periods.
Super Dry reports that its calcium chloride products can hold up to 300% of their dry weight for as long as 90 days.
What are molecular sieves used for?
Molecular sieves are synthetic zeolites engineered with uniform pores that target specific molecules like water.
They are common in gas and liquid drying, medical oxygen concentrators, and other ultra-low humidity applications.
Are these companies suitable for pharmaceutical packaging?
Several are, with Clariant producing desiccants in ISO 15378 GMP certified facilities and Sorbchem India supplying pharmaceutical coils and bags.
Buyers in regulated sectors should always confirm current certifications directly with each manufacturer.
How do I choose the right desiccant supplier?
Match the supplier to your application, required certifications, shipping conditions and sustainability goals.
Reviewing each company’s official product data is the most reliable way to compare options before committing.
Can desiccants be reused or regenerated?
Many adsorbent desiccants like silica gel and molecular sieves can be regenerated by applying heat to drive off the trapped moisture.
Calcium chloride desiccants, by contrast, are typically single use because they dissolve as they absorb water.
