Type A White Silica Gel Beads
sSORB AW is a purified Type A white silica gel manufactured from synthetically modified silicon dioxide and processed into hard, smooth beads. Its internal structure contains an extensive network of narrow, interconnected pores that creates a large surface area with a strong affinity for water vapor.
The product is white to clear in appearance and has a nominal pore opening of 20–30 Å. It can adsorb moisture at temperatures as high as 220°F, although its preferred operating conditions are approximately 70–90°F and 60–90% relative humidity.
sSORB AW is available in three particle-size ranges. The principal published distinction among the grades is bead size; each grade carries the same Type A classification, pore-opening range, adsorption-capacity requirements, bulk-density specification, and package-moisture limit.
Typical Applications
sSORB AW white silica gel beads are used in compressed-air dryers, desiccant packets and other protective packaging formats, catalyst-carrier applications, and general industrial moisture-control systems.
Packaging Information
sSORB AW white silica gel beads are available in:
- 55 lb (25 kg) bags
- Made-to-order super sacks
Bead-size availability, order quantities, packaging requirements, and current lead times should be confirmed with Interra Global.
