Plasticizers
Plasticizers, acting as swelling agents, increase the plasticity of a body. These additives absorb a portion of the available preparation water and increase the workability of the body, thanks to their swelling ability. This makes it possible to manufacture extrusion bodies based on non-plastic powder metallurgical raw materials.
On account of extrusion body surfaces being dull in many cases, it is recommended to combine plasticizers with pressing agents and lubricants.
