Non-indicating – Silica Gel


Non-indicating Silica Gel, appearing as beads or in granular form, is tough, hard, and resembles glass. This product is a desiccant and is typically used in a static application to dry and maintain the humidity of a contained area. Using Silica Gel for shipment and storage will help prevent the rusting of instruments, gauges, and equipment that is exposed to humidity such as guns and ammunition in a gun safe.

Product Application

White Silica Gel is often used for drying and moisture-proofing, commonly found in small desiccant packages, which help maintain humidity during shipment and storage of goods. White Silica Gel can also be used as a catalyst carrier, separator, variable pressure adsorbents, and more.
