silicagel 200_200Silica gel blue is another option for controlling moisture which is obtains cobalt chloride in it. When silica gel is absorbing moisture, gel’s beads color is change from blue to purple to pink, this is indicate the gel needs to be replaced or regenerate. The reason behind is cobalt chloride. The creation and removal of blue silica gel is difficult because cobalt chloride is toxic.Blue silica gel is also available crystals foams which absorb approximately 8 percent of its weight in water. It is DMF free, non-corrosive, non-toxic, odorless and tasteless.
Self-indicating silica gel is non-hazardous and indicating type, we can identify silica gel being full of moisture which can absorb a big amount of water from internal surface area. Silica gel control many substances including aromatics,HC1 and CO2 without reacting other substances and destroying toxicity. It consistent change shape and size of silica gel desiccant.
