Mineral Desiccant is an effective means of moisture proof, can absorb moisture from the air, usually used in a sealed environment to reduce the humidity of the packaging, and prevent the product from moisture damage.
How Mineral Desiccant works
It works by absorbing water molecules into their own structure in a physical way, or after absorbing water molecules, it changes its own chemical structure and becomes another kind of material.
Silica Gel Desiccant: nice appearance, one-way adsorption, good stability of thermal and chemical properties, high strength.
Topsorb mineral desiccant sachets are non-toxic, non-corrosive, environmental friendly, without any negative effects, DMF free. It has varies of specifications.
Packaging weight
Mini Dry: 10g, 20g, 30g, mainly used for sealed package of products, such as PE bag, aluminum foil bag, anti-static bag, boxes, etc.
Close Dry: 50g, 100g, 200g, 250g, mainly used mainly in sealed package of cartons, wooden cases, containers, etc.
Mini Dry, Close Dry Absorbent
Active Mineral: Low cost, fast performance, high adsorption capacity, non-toxic, tasteless, non- corrosive, and pollution-free.
Clay: 100% nature, low cost, good performance in low humidity environment (at <30%RH, such as the vacuum package of PCB circuit board).
