Silica gel white is semi-transparent glassy crystals used as moisture absorbent. It also known as Non Indicating type Silica gel. The beauty of white silica gel is the physical adsorption of water vapors into its internal pores. There is no chemical reaction, no by products or side effects. Even when saturated with water vapors, silica gel still has the appearance of a dry product, its shape unchanged. Its work and requires replacement or regeneration. In fact, it is mainly use as dehumidification and moisture absorption in sealed vessel.
