Silica Gel Desiccant


Silica Gel Non-Indicating

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. Also, white silica gel helps in preventing moisture, 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 pharmaceuticals, compressed air dryers, electronics product packaging, dehumidification process, dehydrated foods etc.
