Abstract
Polymer-bound adsorbent beads are usable as a direct replacement for conventional clay-bound beads in insulating glass unit manufacture to eliminate the problem of dusting associated with conventional beads. Polymer-bound beads provide good adsorption and superior crush strength compared to clay-bound adsorbent beads previously used in insulating glass units to desiccate the space between the glass panes. The polymer-bound adsorbent beads may also be used as a substitute for conventional desiccant beads in water adsorption applications such as in bottle stoppers, sachets, blister packaging, etc.
