Blue silica gel, also call "Color-changing silica gel " is an indicator adsorbent with high added value and high technical content after deep processing, which is made from fine porous silica gel, a highly active adsorbent.
blue silica gel is ideal as a primary desiccant or blended with other desiccants in any application where visual control of moisture is required. sSORB silica gel beads are saturated with a moisture indicating solution that gives them a deep blue color when dry. The color changes from blue to purple to pink as it adsorbs moisture.

Application
(1) Moisture absorption and rust prevention mainly used for instrumentation equipment in an airtight conditions, at the same time, through its color changing from blue to red after moisture absorption intuitive indicates the environmental relative humidity;
(2) Used with ordinary silica gel desiccant, indicates the degree of desiccant moisture absorption and judges environment relative humidity;
3) As packing silica gel desiccant, widely used for precision instrument of leather shoes, clothing and household appliances such as food and drug administration.
