Cobalt-free desiccant

Indicating silica gel for industrial applications

Orange silica gel is a high-quality desiccant designed to control moisture and protect products during storage and transportation. It is made from high-purity sodium silicate and provides reliable moisture absorption for a wide range of industrial applications.

The silica gel contains a porous structure with an average pore size of approximately 2.4 nanometers, allowing it to effectively absorb and retain moisture from the surrounding environment. This helps prevent damage caused by humidity such as rust, mold, and product deterioration.

Our orange silica gel is cobalt-free and environmentally friendly, making it suitable for export and compliant with international environmental standards. It is also non-toxic and free from restricted substances such as Dimethylformamide (DMF), ensuring safe use in sensitive industries.

The desiccant includes a color indicator feature, where the orange beads gradually turn green when moisture absorption capacity is reached, making it easy to monitor when replacement is required.
