The selection of an appropriate binder system is dependent on the physical and mechanical properties of the powders being extruded. It is important to select a fugitive binder that can be completely removed, as residual contaminants can degrade the mechanical properties of the finished product. To facilitate proper rheological behavior, binder formulations may contain several components, including solvents, surfactants, deflocculants, coagulants, lubricants, plasticizers, and preservatives.
