3. Packing: 25kgs/bag, 25kgs/drum, 150kgs/drum, 800kgs/bag
4. Color change: Blue to pink
Silica Gel Blue sachet: 0.5g, 1g, 2g, 3G, 4G, 5g, 6g, 10g, 100g, 500g, 1000g, etc.
Silica Gel Blue is produced by white silica gel added with ammonium tetrachlorocobaltate(II) (NH4)2CoCl4 or cobalt chloride CoCl2. This will cause the gel to be blue when dry and pink when hydrated.
Silica Gel Blue semi-transparent glassy substance containing an indicator as "Cobalt Chloride" a heavy metal salt. When free from moisture the Granules or beads are dark blue in color. As the beads takes up moisture, they turns to light blue gradually & When they turn pink, When the gel has absorbed approximately 8 % percent of its weight in water the colored crystals will turn from blue to pink making an easy visual indicator of whether the gel has become saturated with moisture. It indicates that the gel needs to be replaced or regenerated. The indicating silica gel will still adsorb up to 40% of its weight in water vapor just like the non-indicating In fact, it is mainly used as indicator for the extent of dehumidification and moisture absorption in sealed vessel and Silica Gel Breather Industry. Blue Silica Gel is also know as Indicating Silica Gel, Self Indicating Silica Gel, Blue Desiccants, Moisture absorber.

Use:
Mainly used for absorbing moisture, anti-rusting 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.
