Simplely comparison about all kinds of desiccant you can choose the right dry agent here
- Oct 30, 2018 -

We have many kinds of dessicant here for your optional like silica gel desiccant, mineral clay desiccant, polymer desiccant, calsium chloride desiccant, montmorillonite desiccant.


Each type of desiccant have its own advantages, you can choose the right desiccant according to your product's features. The following comparison sheet can be your reference.

Advantages

Silica gel

Transparency/blue/orange

(25℃,RH=20%)>10%

(25℃,RH=40%)>20%

(25℃,RH=90%)>30%

Shoes, Electronics, Food, Pharmaceuticals, Nutraceuticals, Garment, Leather

The active adsorbent has no smell no taste and non-toxic. The features a stable chemical property and never reacts with any substance except the alkali and hydrofluoric acid. The most safe desiccant for foods and Pharmaceuticals.

Mineral clay

beads

Grey

(25℃,RH=20%)>15%

(25℃,RH=40%)>25%

(25℃,RH=90%)>38%

Shoes, Food, Garment, Plastics, textile, Consumer products(wardrobe, bedding, shoes and so on

Desiccant clay is the most cost effective products that businesses use for protection against moisture. Non-toxic, free from pollution, decompose naturally.

Polymer

powder

White

(25℃,RH=90%) ≥ 300%

Food, Shoes, Plastics etc.

Environment protection, non-toxic. Strong moisture absorption, no leakage. Absorbs up to 300% of its own weight from -5℃-90. After the desiccant absorb the moisture the polymer would turn to gel and when arrived the most capacity, few moisture would be evaporated.

Calcium chloride

powder

White

(25℃,RH=90%) ≥ 200%

Container, garments(cloths, textile,shoes),  packaging cartons, boxes, pallets,etc

high efficient desiccant absorption rate with high speed. The calcium chloride powder would turn to gel or liquid after absorb high rate moisture, so it usually added some polymer and packaged with better material.

Montmorillonite Clay

gravel

Grey

25℃, RH=20%, ≥11%

25℃, RH=40%, ≥18%

25℃, RH=90%, ≥30%

Semiconductor, Electronic Component, Hardware, Military Products, Precision Instrument, Precision Measuring Instrument

The raw material of the eco-friendly desiccant is purely natural montmorillonite clay. Do not contain any additives and chloride, cheaper and stable moisture absorption capacity.
