Composed of blue gel indicator, allochroic silica gel and blue gel, blue silica gel performs as blue or light blue glasslike particles in the spherical or lumpy shape. It will change color from blue to red after adsorbing moisture.

Application:

- Absorbing moisture for apparatus, instruments, and equipments in airproof condition to avoid from rusting, indicating the environmental relative humidity due to its obvious color change.

- Indicate desiccants’ absorbing degree and environmental relative humidity by being mixed with common silica gel in proportion. Besides, it is also used in precision apparatus, leather, shoes, garment, food, drug and household electric appliance industries as silicon gel desiccant.
