ugsichemicalfeed.comDry polymer is very hygroscopic (moisture-attracting), so care should be taken to store it in a cool and dry area (neither above 40 °C [104 °F] nor humid). Dry polymer has a shelf life of over 3 years if unopened and properly stored. Once a bag is opened, dry polymer can quickly clump and become unusable.

Injection Molding - Massachusetts Institute of Technology
web.mit.eduAn extruder is used to mix additives with a polymer base, to bestow the polymer with the required characteristics. Similar to an injection molding machine, but without a mold and continuous production. Thus it has a similar energy consumption profile.

Dry Electrode Coating Technology
www.powersourcesconference.compolymer binder is not dissolved; as a result, the binding mechanism is an inter-connecting network comprised of point-contacts with the active material particle surface. This dry binding structure is less obtrusive and, consequently, enables lithium ions better access to the active material particles. This feature is especially advantageous for ...
