Silica Gel can adsorb up to 40% of its weight in moisture and has the highest absorption capacity of any commercially used desiccant. Our Blue Silica Gel beads are Self Indicating the blue beads change to pink indicating the silica gel has become exhausted and should be replaced or regenerated.

Silica Gel is used where processes and products need to be protected from the negative consequences of humidity and moisture: such as:

  • Breathing filter for electric transformers
  • Silos and storage tanks
  • Packing material
  • Laboratories
  • Home and hobby
  • Boating, Yachts
  • Sports equipment

Reactivation Instructions

The blue /white silica gel beads we supply are auto-indicating – the blue indicator beads change from Blue (when active), to Pink when it is no longer active (saturated).

Once the Silica Gel is no longer active, it is easy to re-activate by heating the granules in an open container in your oven, at a temperature of between 105 and 110°c. When the indicating granules return to their original colour blue, let the Silica Gel cool and then store it in a sealed container until you are ready to use it again.
