Activated Clay Desiccant

Activated Clay Desiccants
Principle
They appear as tough globose granules. After filtered from Attapulgite mine, ground-granulated-activated under high temperature, innoxious, harmless and degradable. The ability of moisture absorption is 3 times as silica gel. The heavy metal content is lower than ROHS and Sony GP.
Applicable Scope
Suitable for dehumidification of computer related products, sophisticated machinery, semiconductor industry and food industry.
