Silica gel is a porous and granular material composed of silica, a form of silicon dioxide. It is widely used as a desiccant to control moisture levels in enclosed spaces or packaging. Silica gel is typically manufactured with an indicator, such as cobalt chloride, which gives it an orange color when it is dry. However, as it absorbs moisture, the color changes from orange to colorless, indicating the saturation of the silica gel with water vapor.
Silica Gel Orange is a high-performance moisture-absorbing desiccant widely used to protect products from humidity damage during storage and transportation. It is a cobalt-free indicating silica gel that changes colour as it absorbs moisture, making it easy to monitor the saturation level. The color change from silica gel orange to green clearly indicates when the desiccant has absorbed moisture and reached its saturation level.
Designed for safe and efficient moisture control, Silica Gel Orange is commonly used across industries such as electronics, pharmaceuticals, packaging, logistics, chemicals, and food storage.
Unlike traditional blue silica gel that contains cobalt chloride, orange silica gel is a safer and environmentally friendly alternative. It provides reliable humidity control while eliminating the health and environmental risks associated with cobalt-based desiccants. This silica gel orange to green colour transition helps users easily monitor moisture absorption in real time.
