OBRA desiccant clay is primarily used in form of desiccant bags made according to DIN 55 473 to protect products which are sensitive to humidity. In addition, OBRA desiccant clay can also be used for the static dehumidification of air and other gases, for example in chemical and pharmaceutical manufacturing, clean rooms and drying rooms, etc.
OBRA desiccant clay is a natural calcium bentonite consisting of approx. 90% montmorillonite. Calcium bentonite has a layer structure. It is able to reversibly adsorb water molecules to its inner surface area. Oker-Chemie supplies OBRA desiccant clay in big bags with inlaid polyethylene bags of up to 1,000 kg net weight.
