Silica Gel Non-Indicating
Non-Indicating silica gel will not change its color while absorbing moisture. This is commonly used in packets. Mainly, White silica gel beads and crystals come under the non-indicating category.
White silica gel prefers to absorb water and other substantial-quality containing HC1, CO2, gasoline hydrocarbons, nitrogen, sulfur and aromatics compounds with a high capacity of moisture. For this reason, white silica gel prevents moisture, damage, spoilage, and growth of mold from packaging materials.
Silica gel crystals are always used in the dry product even when they are saturated with water and it is the most famous desiccants that are been used from many applications such as compressed air dryers, dehumidification process, dehydrated foods, pharmaceuticals, electronics product packaging.
