Character: Composed of blue gel indicator, allochroic silica gel and blue gel, blue silica gel performs as blue or light blue glasslike particles in the spherical or lumpy shape. It will change its color from blue to red after absorbing moisture.
Use
1. Mainly used for absorbing moisture, anti-rusting of instruments, gauges and equipment in the enclosed conditions.
2. After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.
3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the relative humidity of a given environment.
4. As a silica gel drier, it is widely used as silica gel drier for the packing of precision instruments, leathers, shoes, clothes, foodstuffs, medicines and household electric appliances, etc.
