The Blue Silica Gel (Indicating Type Desiccant Silica Gel) is a semi-transparent glassy substance, containing an indicator as “Cobalt Chloride” a heavy metal salt. The Granules or beads are dark blue in color when they are free from moisture. As the graduals take up moisture, they turn to light blue gradually, When Dark Blue Silica Gel’s color of crystal turns from blue to pink, or color less it has absorbed approximately more than 8 % percent of its weight in water making it an easy visual indicator to see whether gel has become saturated with water. It shows whether the gel needs to be replaced or regenerated. The indicating silica gel will still adsorb up to 40% of its weight in water vapor just like the non-indicating. In fact, it is mainly used as indicator for the extent of dehumidification and moisture absorption in sealed vessel and Silica Gel Breather Industry & Transformer Industry. We have an illustrious reputation of delivering high quality Blue Silica Gel. The quality blended with reasonable pricing makes us one of the prominent Blue Silica Gel or Indicating Silica Gel Desiccant Manufacturers and Suppliers. Some times it is also know as Blue to Pink Silica Gel.
