Silica sand has ability to adsorb up to one third of its own weight in water vapour. This adsorption efficiency is approximately 35% greater that typical desiccant clays, making Silica sand the preferred choice where weight or efficiency are important factors.
Silica sand has an almost indefinite shelf life if stored in airtight conditions.
Silica sand can be regenerated and reused if required. Gently heating silica sand will drive off the adsorbed moisture and leave it ready for reuse.
Silica sand is a very inert material, it will not normally attack or corrode other materials and with the exception of strong alkalis and hydrofluoric acid is itself resistant to attack.
Silica sand is non-toxic and non-flammable.
Silica sand is most frequently and conveniently used packed in a breathable sachet or bag. These are available in a wide range of sizes suitable for use with a wide range of applications.
