Silica Gels
Silica Gel - Bead Form, Conditioned
All exhibition cases need some form of relative humidity buffering to control and protect the enclosed contents from excessive RH changes. Our high capacity beaded silica gel is the best choice for controlling relative humidity within the 0-30% RH range. The beaded form offers low abrasion which greatly reduces breakage of the gel, thus producing far less dust and extends the service life of the gel. Silica gel is an amorphous, extremely porous form of silica. Its action in absorption and desorption of moisture is purely physical and there is no change in size or shape of the particle as it absorbs moisture. Our high capacity beaded silica gel is comprised of smooth beads 1/8" (2 - 4mm) in diameter with a mean pore diameter of 20-25 angstroms and has a specific surface area of 700-750 m2/g. Our high capacity beaded silica gel can absorb 40% of its own weight of water. The silica gel has an as shipped RH of 5 to 30%. For a weight to volume reference, the bulk density of the gel is 47 lbs. per cu ft. or approx. 6 lbs. to a one gallon container.
