Looking to import High hygroscopic Moisture Absorber directly from China?We specialize in OEM and wholesale solutions for importers, wholesalers, retailers, and brand owners worldwide.
SORBSTAR Magnesium chloride desiccant is a powerful moisture absorber made from anhydrous magnesium chloride (MgCl₂) and starch-based polymer. It quickly absorbs moisture from the environment through a chemical reaction, turning into a solid block, which ensures safe and leak-free performance. This property ensures it remains leak-proof, safe, and ideal for use in various enclosed environments. With high absorption capacity and excellent performance in high-humidity conditions, it’s a reliable solution for protecting your goods from mold, corrosion, and moisture damage.
The packaging uses durable Tyvek® Paper/Dulai Paper materials that are dust-proof, wear-resistant, and corrosion-resistant, effectively preventing dust leakage and enhancing moisture protection.
Available in various formats including hanging strips, sachets.
All our desiccants are tested and certified to meet global export standards, Our silica gel desiccant products comply with REACH and ROHS standards, and we can provide SGS product test reports, halogen and sulfur element test reports, and MSDS chemical composition reports.

Leak-Free Solidification: Moisture becomes a solid mass — no dripping, even under pressure
Reinforced Packaging: Breathable HDPE fabric and Tyvek® Paper/Dulai Paper composite to resist dust, tear, and chemical wear
Safe & Compliant: Free of DMF; meets RoHS, REACH, and international safety standards
Custom Sizes Available: 2g, 5g, 10g, 25g, 50g, 100g, or tailored to your specifications
Tyvek® Paper/Dulai Paper – Packet Material
When exposed to moisture in the air, anhydrous magnesium chloride undergoes a chemical reaction that absorbs water molecules and transforms the powder into a solid mass. This process prevents reverse diffusion, ensuring that moisture is permanently trapped.
The gel remains stable and sealed—no leakage, no mess.
The following data is from SGS laboratory test results at 50°C temperature and 90% relative humidity.
