Silica Gel

Silica Gel

Silica Gel is a conventional desiccant used to adsorb moisture and water vapour due to its odourless and non-reactive characteristics. Silica Gel helps to control relative humidity levels in the surrounding environment, adsorbing up to 40% of its weight and lowering relative humidity down to 40% in an enclosed environment. We offer three types of Silica Gel each with its unique applications; Non-Indicating Silica Gel, Orange-indicating Silica Gel and Blue-indicating Silica Gel.

Non-Indicating Silica Gel

Also known as white or clear silica gel, the Non-indicating Silica Gel is tasteless, non-corrosive, non-toxic, non-reactive to chemicals and odourless, making it a safe moisture adsorbing agent. This silica gel is food safe, allowing it to be packaged together with food products in silica gel sachets.

Blue Indicating Silica Gel

Containing cobalt chloride, the Blue Indicating Silica Gel turns pink from blue when saturated, providing visual alerts for desiccant replacement. It is best suited for use with non-dusting packing of electronic equipment and in applications with visual moisture controls.

Orange Indicating Silica Gel

Known as Envirogel, the Orange Indicating Silica Gel is incorporated with a safe organic indicator known as methyl-violet that changes from orange to green once saturated with water vapour, providing a visual indication to users alerting the need for replacement. It is also an excellent alternative to Blue Indicating Silica Gel as it is heavy-metal free, environmentally friendly, non-toxic and non-corrosive, which makes it more widely applicable.
