Property
Blue silicon gel is divided into blue gel indicator, color-changing silica gel and blue gel in the form of blue or light blue vitreous body, divided into sphere and block types according to form of granules; blue color will turn into red after absorption of moisture.
Purpose
1.Fit for absorption of moisture and rust resistance for instrument, meters and equipment under airproofing condition, relative humidity of atmosphere will be indicated as blue color will turn into red after absorption of moisture.
2.Moisture absorption and relative humidity of indicating drier can be showed matched with common silicon gel drier. As silicon gel drier, it is widely used for precise instrument, leather, shoes, costume, food, pharmacy and household apparatus.
