  • Patent number: 6777481
    Abstract: The incorporation of waxes into thermoplastic adsorbent compositions enables the formation of high adsorbent loading compositions which have suitable flowability properties. The wax-containing thermoplastic adsorbent compositions are especially useful as thermoplastic adsorbent adhesives for use in desiccating interior compartments of insulating glass units.
    Type: Grant

  • Patent number: 6112888
    Abstract: A substantially solvent-free molten or fluid desiccant/organic matrix composition is adhered to a package whereby the desiccant is in communication with a compartment of the resulting package such that the compartment is desiccated by the desiccant composition. The desiccant composition preferably contains a thermoplastic organic matrix, is heated before it is adhered to the package, and cools after application. In some instances, the desiccant matrix may be adhered to a component of the package contents. The package is preferably non-reclosable and suitable for holding an article such as a drug, medical device or electronic device.

  • Patent number: 5879764
    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.
