Activated Montmorillonite Clay Desiccant

Clay desiccant is the least expensive of all desiccants and is a naturally occurring non-hazardous mineral composed of magnesium aluminum silicate (a calcium aluminum silicate type of hydros clay). Montmorillonite clay is used in most industrial applications requiring humidity control because it recharges easily and does not swell as it adsorbs water vapor.


  • Natural material , quick&high absorption capacity.

  • Non-toxic and non-corrosive , Eco-friendly product.

  • Cheap price , high quality.

Detail intruduction
