Blue Silica Gel
Shape: glass-like pellets or lumps.
Color: blue or light blue.
Including blue gel indicator,
chromo tropic silica gel and blue
silica gel.
Turning from blue to red after
absorbing moisture.
-
Mainly used for absorbing moisture, antirusting of instruments, gauges and equipment in the enclosed conditions. After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.
-
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. It is widely used as silica gel drier for the packing of precision instruments, leathers, shoes, clothes, foodstuffs, medicines and household electric appliances, etc.
Size: 1-3mm, 2-5mm, 4-8mm
