Non-cracking in water — protective layer for silica gel beds with free liquid water present.
Adsorbents
Water Resistant Al Silica Gel (Non-Cracking Al Silica Gel)
Description
This product is a white spherical particle, non-toxic and tasteless. Chemically stable, non-combustible and non-cracking in water. It can be used as a protective layer for narrow pore silica gel and narrow pore Al silica gel, and can also be used alone where free (liquid) water content is high. Even with liquid water present in the operating system, this product can achieve a relatively low dew point.
