Pressing agents and lubricants
Pressing agents and lubricants optimise the shaping properties of extrusion bodies. They reduce internal friction of the body, leading to a more homogeneous compaction and, thus, contributing to a reduction of microstructural tensions. Friction between the article and the mould wall is reduced. An increase in effective mould life is, therefore, possible. The sticking tendencies of the body to the mould wall can also be decreased.
