Silica Gel Blue is a synthetic, amorphous form of silicon dioxide containing an indicator, cobalt chloride, which changes color in response to moisture levels. When in its packed condition and free from moisture, the beads appear dark blue. However, once the Silica Gel Blue absorbs moisture and becomes saturated, it turns pink, indicating that it needs to be replaced with fresh material or regenerated. This self-indicating desiccant is semi-transparent and available in both bead and crystal forms.
The granular gel can absorb up to 40% of its weight in water vapor. When it reaches approximately 8% of its weight in water, the crystals' color changes from blue to light pink. As the beads take up moisture, their color changes to light pink gradually. This blue silica gel is primarily used as an indicator for moisture absorption in sealed containers, particularly in industrial applications where it is supplied in small pouches or bulk quantities. The blue crystals are mainly used in breather transformer applications and are also supplied in bulk quantities. Sorbchem India is a reliable supplier and manufacturer of high-quality blue silica gel beads and crystals, ensuring favorable results and long-term use for food and pharmaceutical products packaging without any hazardous effects.
Silica Gel Blue is a versatile desiccant that can be used in various applications. It is used in transformer industries to monitor moisture levels, in seed and flower drying to preserve the quality of the products, in desiccant pouch manufacturing to ensure the effectiveness of the desiccants, in hearing aid industries to prevent moisture damage, in aerospace and aviation industries to maintain equipment performance, in electronics industries to prevent corrosion, and in automobile and power industries as a desiccant to prevent moisture buildup.
