Silica gel, granules, Chameleon® C 2 - 6 mm drying agent
Silica gel
Non toxic dessicants, for adsorbing moisture from the atmosphere and gas streams, which contain iron salts as a colour indicator. The dry material has an intense orange colour and changes to a pale beige/white colour on adsorption of water.
- Water adsorption capacity at 50% RH is a minimum of 23%
- Loss on drying at 140 °C is less than 2%
- At concentration of 10% in water, pH is from 1,5 to 5
- Regeneration can be achieved by heating to 140 °C in a drying oven
