Silica Gel & Humidity Indication Card (HIC)

Silica Gel is synthetically amorphous silica, which is produced in the form of bead having the appearance of crystals. They can be considered as sponge like structures with a well-defined porosity, which can be varied by altering conditions during manufacturing. Desiccant Silica Gel has a narrow pore structure. This characteristic, couple with its large surface area, gives the product the ability to absorb moisture from air, gases and liquids.

Silica Gel / Dessicant is normally used with Humidity Indicator Cards (HIC)
Applications
· Electronics packaging
· Optical instrument packaging
· Preservation packaging of sensitive components
· Bulk packaging

PHYSICAL PROPERTIES

PRODUCT TYPE

White – A white gel produced in a number of different bead sizes and the capacity to absorb large amount of moisture.
Blue – A blue gel produced by impregnating the white gel with 3% of cobalt chloride.
Blue gel exhibits deep blue coloration, which gradually turns to pink as water is absorbed.
Mix – A mixture of white and blue gels prepared for selected applications.

HEALTH & SAFETY ADVICE

Silica Gel is neither sillcotic nor toxic, but requires sensible handling to minimize the creation of dust. Facemasks should be worn during handling and exhaust ventilation used if available. If eye contact occurs, wash with plenty of water and seek medical advice. Blue gel, indicator grade, contains cobalt chloride: although this is toxic, the low concentration involved obviates the need for special precautions. Care should be taken, however to avoid contamination of food or accidental ingestion. In the event of the latter, medical attention should be sought immediately.
