Silica Gel is a common 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 levels, adsorbing moisture up to 40% of its weight and bring relative humidity down to 40% in an enclosed environment. We provide three types of Silica Gel: Non-Indicating Silica Gel, Blue Indicating Silica Gel and Orange Indicating Silica Gel. We also allow the customisation between the three types of Silica Gel to suit different user needs.
Non-Indicating Silica Gel
Non-Indicating Silica Gel, also known as white or clear silica gel, is odourless, tasteless, non-reactive to chemicals, non-corrosive and non-toxic, which makes it a safe moisture adsorbing agent. The Non-Indicating Silica Gel is food safe, allowing it to be packed together with food.
Blue Indicating Silica Gel
Incorporated with cobalt chloride, the Blue Indicating Silica Gel turns from blue to pink when saturated, providing a visual indication to users that the desiccant requires replacement. The Blue-Indicating Silica Gel is suitable for non-dusting packaging of electronic equipment and in applications with visual moisture controls.
Orange Indicating Silica Gel
Also known as Envirogel, the Orange Indicating Silica Gel contains a safe organic indicator called methyl-violet that changes colour from orange to green when saturated with water vapour, indicating replacement. It is also an excellent alternative to Blue Indicating Silica Gel due to its heavy-metal free, non-corrosive, environmentally friendly and non-toxic properties which makes it widely accepted for a broader range of applications.
Blue and White Indicating Silica Gel – this mixture contains 10% Blue Indicating Silica Gel and 90% Non-Indicating Silica Gel. Orange and White Indicating Silica Gel – this mixture contains 10% Orange Indicating Silica Gel and 90% Non-Indicating Silica Gel (white).
