Silica gel is a granular form of sodium silicate which has the strong ability to adsorb water vapor molecules. Silica gel packets offer a cost-effective way to protect the products against moisture damage during the transportation and storage.Blue indicating silica gel packets contain semi-transparent substance known as cobalt.
They are available in beads or in crystal structure which are used as an indicator for moisture absorption in various industrial applications. The beads or crystals turn into dark blue color when silica gel releases the moisture, whereas light blue color indicates that the beads or crystals have adsorbed the moisture. The pink color beads or crystals mean that the silica gel needs to be regenerated or restored.
Due to the strong adsorption capacity at low relative humidity, blue indicating silica gel packets are widely used in various fields for the drying process. This gel can be combined with non-indicating standard silica gel that comes in white color for the reconditioning once they get saturated.
The gel can be placed in display cases, drawers or desiccant canisters. They can be purchased in a small pouch or in bulk quantity as per your needs and product specifications.
Blue silica gel has the tendency to absorb up to 40% of its weight in moisture. This can easily be observed when the beads get changed from blue state to pink state. As it contains Cobalt Chloride II, therefore it is not recommended for the residential use. Silica gel can remove the moisture at maximum temperature 220ºF, at room temperature from 70 to 90ºF and at high 60 – 90% Relative Humidity (RH).
