A water absorbent chemical that reduces humidity in closed containers thus reducing the possibility of rust, corrosion, mildew, mold and other damage dependent upon ambient moisture. Silica dust can cause respiratory complications, appropriate care should be used.
Bulk Pack - Blue Indicating. Indicates when beads turn pink that maximum absorption of the material has been reached. Beads can be dried at 250 degrees F for approximately 4 hours and then reused.
Bulk Pack - Blue Non-Indicating. Same performance characteristics as blue indicating, but will not change color when maximum moisture retention level has been reached.
Bulk Pack - Mixed. An economical alternative to the use of 100% blue indicating silica. This mix of 90% non-indicating and 10% blue indicating silica allows for quick identification when the maximum absorption level has been reached.
