Silica Gel is a common desiccant used to adsorb moisture and water vapour due to its odourless and non-reactive characteristics. It helps control relative humidity levels in the surrounding levels, adsorbing moisture up to 40% of its weight and bringing relative humidity down to 40% in an enclosed environment. We supply the main three Gel, Non-indicating Silica Gel, Blue Indicating Silica Gel and Orange Indicating Silica Gel.
Non-indicating Silica, also known as white or clear silica gel, is odourless, tasteless, non-reactive to chemicals, non-corrosive and non-toxic, making it a safe moisture adsorbing agent. The Non-indicating Silica Gel is food safe, allowing it to be packed together with food.
Incorporated with cobalt chloride, the Blue Indicating Silica Gel turns from blue to pink when saturated, indicating 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.
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, making 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).
It absorbs moisture faster than desiccant clay at higher humidity levels. Made of highly porous silicon dioxide, it binds water molecules to its interior surfaces and keeps it dry even after it is saturated. The desiccant is a mineral processed and purified into a granular or beaded form. The moisture absorbers are often packed into desiccant bags to help eliminate humidity and moisture from the air, creating a dry and moisture-free environment for product packaging in the electronics, food, automotive, and healthcare industries. Stream Peak desiccants are controlled and closely monitored with our in-house laboratory daily to ensure high-quality grade desiccants supply with high dust attrition resistance.
