Silica gel Orange
Silica Gel Orange is an indicating desiccant available in spherical and irregular bead forms with an orange appearance. Its main ingredient is SiO₂, and it changes color from orange to green as it absorbs moisture, providing a clear visual indication of humidity levels.
It is mainly used as a drying agent and humidity indicator across power, pharmaceutical, food, petroleum, precision instrument, leather, textile, military, and other industrial applications. Its high surface area and moisture adsorption capacity make it suitable for effective moisture control.
