Appearance：
Blue transparent or translucent glass-like silica gel, available in spherical beads and irregular granules.
Product Description：
Blue Silica Gel is a color-indicating desiccant composed primarily of silicon dioxide (SiO₂) and a moisture-sensitive indicator. It changes color from blue to pink as moisture is absorbed, providing a clear visual indication of its adsorption status. With excellent moisture adsorption capacity and reliable humidity indication, it is widely used for moisture control, industrial drying, equipment protection and packaging applications.
Features：
Excellent moisture adsorption capacity
Clear color change from blue to pink
Visual indication of moisture saturation
High mechanical strength and abrasion resistance
Stable chemical properties
Regenerable through heating for repeated use
Applications：
Industrial gas and compressed air drying
Moisture protection for electrical equipment and precision instruments
Packaging desiccant for electronics, optical devices and machinery
Storage protection for pharmaceuticals and chemicals
Humidity indication in sealed containers and drying systems
Cobalt-Free Blue Silica Gel
In addition to conventional Blue Silica Gel, we also supply Cobalt-Free Blue Silica Gel, which provides the same moisture indication function without using cobalt chloride. It is an environmentally friendly alternative suitable for applications with specific environmental or regulatory requirements.
Packaging
15kg or 25 kg composite bags
150 kg fiber drums or steel drums
500 kg or 750 kg jumbo bags
Customized packaging available upon request
Storage：
Store in a cool, dry and well-ventilated place. Keep the package tightly sealed before use to prevent moisture absorption. Avoid exposure to direct sunlight, rain and high humidity.
Customization：
Particle size, packaging and technical specifications can be customized according to customer requirements.
