Magnesium Chloride Desiccant

Over 200% absorption capacity — among the highest of any desiccant type. Magnesium chloride desiccant absorbs more than twice its own weight in moisture, then converts from powder to a solid gel that cannot spill or leak back, even if the sachet is punctured.

That extreme capacity makes it the right choice where space is tight but humidity is severe: car headlights and lamp housings, sealed electronics enclosures, optical equipment, and long-voyage container shipments. One small magnesium chloride sachet often replaces several times its weight in ordinary silica gel.

Supplied manufacturer-direct with consistent granulation and sealed in high-barrier packaging, it is available in multiple sizes with OEM branding on request. Ask our team to compare it against calcium chloride and silica gel for your specific application — we will recommend whichever chemistry genuinely fits best.
