Silica Gel

Silica gel is a desiccant with odourless and non-reactive properties. The absorbent beads have a highly porous structure, which gives them a large surface area for adsorbing moisture. They efficiently adsorb moisture and controls relative humidity by up to 40% in enclosed environments.

Effective Moisture Absorption

Desiccants are used in different applications like medication bottles, food packaging, drying flowers, preventing mould in shoes, and electronics packaging. We offer three types: Non-Indicating, Orange-Indicating, and Blue-Indicating.

Non-indicating silica gel, also known as clear or white silica gel, is non-corrosive, non-toxic, and odourless. It is a safe moisture-absorbing agent suitable for food packaging, maintaining its appearance even when saturated with moisture.

Blue-indicating silica gel contains cobalt chloride. It starts as blue when dry and transitions to pink as it becomes saturated. This colour shift provides a clear visual signal of the moisture-absorption level, determining when the silica gel requires regeneration or replacement. It is useful for electronic equipment and visual moisture control.

Combat Dampness and Humidity

Orange-indicating silica gel is a type of silica gel that changes colour as it adsorbs moisture. Initially orange, when dry, it transitions to green as it becomes saturated. This visual indicator helps gauge its moisture-absorbing capacity and indicates when it is time for replacement or regeneration. The moisture absorber uses the organic indicator methyl-violet making it an eco-friendly, non-toxic alternative.

The drying agent can be regenerated by heating it to remove the absorbed moisture. Silica beads have a long shelf life and can be stored for extended periods without losing their moisture-absorbing properties. We subject all our silica gel desiccants to rigorous testing in our QA laboratory, adhering to ISO 9001 certification guidelines.
