Silica Gel White

Silica Gel White (Non Indicating Type Silica Gel)

In this type all the particles of Silica Gel are not impregnated with any Kind of indicating agent. When free from moisture the particles are transparent white. As they are put to use, the particles take up moisture, Silica Gel gradually turns little milk or hazy in whiteness, these Silica gel always has higher capacity for Moisture uptake than any indicator type Silica Gel. These can be regenerated in dryers or inside dehumidifiers.
