Calcium Chloride Desiccant

Built for Heavy Moisture Loads

Calcium chloride desiccant absorbs up to 300% of its own weight under test conditions — several times the capacity of silica gel. As it absorbs, it converts moisture into a gel that stays locked inside the pouch instead of leaking.

Double-Layer Leak-Proof Construction

• Inner layer: American TYVEK white film + PET plastic film

• Outer layer: non-woven composite breathable film

• Purity: 99.8% calcium chloride

• Working range: -5°C to 90°C

NW Series: 2g to 250g

Nine standard weights cover everything from small cartons to pallets. Each weight is a fixed SKU, so reorders are exact and traceable.

When to Choose It Over Silica Gel

Choose calcium chloride when the moisture load is high, the shipment is long, or the cost per gram of water removed matters. Choose silica gel when the package is small and a dry, free-flowing granule is preferred. Our engineers will confirm the choice against your conditions.
