Non - Indicating (White) Silica Gel

White Silica Gel

Non-indicating (white) silica gel will not indicate any colour changes when they are becoming saturated because of no indicator used during manufacturing process. Means Non-indicating (white) silica gel crystals will remain white when they are becoming saturated. This kind of silica gel is commonly used in preserving some items and to reduce humidity in storage. Non-indicating (white) Silica is one of the oldest and most popular desiccant and adsorbent used for a wide number of industrial and consumer applications.
