in broad terms , this process adds organic material to particulate solids and works the mix . resolification in a unique way creates improved binding of the particulate solids . the particulate solids are materials such as metal , semi - metal , ceramic , glass , plastic , or rubber , alloy , composite , agglomerate , or other organic . the organic selection should remain solid in handling and may become liquid during compaction . these materials may consist of a liquid , solid or mixture selected from the group consisting of fatty acids ; and amides , bisamides , soaps and salts of fatty acids , waxes , resin , oils , hydrogenated fats and oils , polymers , mold release or friction reducing agent . with lubricity enough to enable ejection of a molded compact , flow and adequately low molecular weight and formulation to enable clean burn off if desired . with inputs that may include either pressure , solvents , chemical activation of polymers , or thermal heat ; and working so as to enhance the gluing of particulates together and rounding of the agglomerate to provide flowability .
