Silica Gel Desiccant Forms
Silica gel desiccants are available in various packaging formats, including packets, canisters, and larger bags.

Packet
These are small, individual packets or sachets containing silica gel. They are easy to handle and distribute, but with limited absorption capacity.

Canister
These canisters usually have small holes or perforations to allow air to flow through while trapping moisture. They have a larger capacity than individual packs.

Large Bag
Larger bags filled with silica gel are used for industrial or commercial moisture control, as they have a higher moisture-absorbing capacity.
Silica Gel Beads
Silicon dioxide (SiO2) beads are small, porous, and granular particles. They are available in various sizes and colors, with the most common color being a transparent, white, blue or orange hue.

Transparent
These are standard silica gel beads without any color indicator. They absorb moisture effectively but do not change color during the process.

White
White silica gel beads have a slightly opaque or milky appearance. They are also used for similar applications as transparent silica gel beads.

Blue
Also called "indicator silica gel", they contain a moisture-sensitive cobalt chloride indicator that changes color as the beads absorb moisture.

Orange
Another type of indicator silica gel, use a moisture indicator that changes from orange to green when beads are fully saturated with moisture.
