  • Description

1.It will adsorb up to 34%of its own weight in water vapour. This adsorption efficiency is approximately 30 greater than typical desiccant clays, making silica gel the preferred choice where weight or efficiency are important factors.
2. It has an almost indefinite shelf life if stored in airtight conditions.
3. It can be regenerated and reused if required. Gently heating silica gel will drive off the adsorbed moisture
and leave it ready for reuse.
4. It is a very inert material, it will not normally attack or corrode other materials and with the exception of
