What is Silica Gel?

Silica gel packets are small pouches that are filled with a gel, which is called silica, that absorbs moisture from the area where it is kept. This is an important property of this product, which is why it is commonly used as a drying agent. We can see these small white packets in bags, electronic devices, shoe boxes, water bottles, etc. Though ignored by us, these packets have many interesting uses and properties, which we are going to read about here in this useful article about silica gel.

What are silica gel packets?

This packet contains the naturally occurring mineral silica gel, a porous and granular form of silicon dioxide. Silica gel is commonly used in industrial and commercial applications due to its ability to absorb moisture from the environment. Due to its property as an efficient desiccant, it is mostly used in products that need to be protected from moisture damage.

How do silica gel packets work?

The major function of this packet is to absorb moisture from the surrounding environment. Silica gel is highly absorbent; it can attract water molecules to its surface and then hold them. When it is placed in an enclosed space like shoe boxes, bottles, or bags, it absorbs moisture gradually to its maximum capacity. Once it is saturated with moisture, it will be of no further use and need to be replaced with a new one.
