SILICA GEL

Silica gel is an amorphous form of silicon dioxide, which is synthetically produced in the form of hard irregular granules hard regular beads.  It is the structure that makes silica gel a high capacity desiccant. Water molecules adhere to the Silica Gels surface because it exhibits a lower vapour pressure than the surrounding air. When equilibrium of equal pressure is reached, no more adsorption occured, thus the higher the humidity of the surrounding air, the greater the amount of water that is adsorbed before equilibrium is reached.

Silica gel can adsorb about 40 % of its weight in moisture and can take the relative humidity in a closed container.

Even when saturated with water vapour, silica gel still has the appearance of a dry product, its shape unchanged. It is non-corrosive, odorless, tasteless, non-toxic, and chemically inert

​

Silica gel serves to eliminate humidity by eliminating moisture from the air creating a dry and moisture-free environment for custom product packaging like electronics, cosmetics, medication, and apparels, etc. that are at higher risk of damage. Leather gets mold if not kept dry properly. That is why items like these come with the silica packets inside the box.
