Safety Data Sheet:



White Silica Gel (sSORB® Type-A)  is a synthetically modified silicon dioxide that has been purified and processed into a hard, smooth bead. sSORB silica gel’s high surface area has a vast network of narrow interconnecting pores which have a strong affinity for moisture. Silica gel will remove moisture at temperatures as high as 220° F, but is best used at room temperature (70-90° F) and high relative humidity (60-90% rh).

Granular silica gel is synthetically modified to give it a vast internal network of interconnecting cavities creating a very large internal surface area for adsorption as a desiccant. Silica gel’s signature characteristic is its ability to adsorb moisture in humid environments and performs best at 60 – 90% relative humidity at ambient temperature.

Granular  Applications:

Given its high affinity for water, sSORB granular white silica gel is used:

  • in the gas industry to dry natural gas,
  • as a desiccant in packaging (silica packets),
  • for protecting cargo, electronics, vitamins, pharmaceuticals, foodstuffs
  • and also in compressed air dryers.

White Silica Gel Bead Applications:

sSORB silica gel is frequently used in:

  • compressed air dryers,
  • in desiccant packets to protect products,
  • as a catalyst carrier,
  • and, generally, in any desiccant application requiring premium performance, high capacity, and energy savings.

Handling & Storage Recommendations

Reseal white silica gel packages and store in a dry location to prevent unintentional water adsorption. Do not store super sacks outside; ultraviolet radiation and other adverse conditions will negatively impact its integrity and may eventually cause the bag to fail. We recommend that you rotate stock so the oldest material is used first.
