Montmorillonite Desiccant Series Wisesorbent Technology

Wisesorbent Montmorillonite Series Desiccant
Physical Adsorption Desiccant

Montmorillonite Desiccants are for industrial packaging and use high strength filter paper (1g -30g) or coated non-woven fabrics (50g-500g) as packing material and montmorillonite as its main adsorbent. This clay is a physical absorbent and great to use together with metal products, it has high moisture absorption rate at low humidity and is non-corrosive, non-toxic and does not contain any chemical additives. A great moisture fighter and a natural environmentally friendly one too!
