Flow optimization in high-speed extruders

Case study: how the Plectus PE wax package cut 14% of the energy consumption on a technical hose line.

Signs of rheology outside the window

Amperage oscillation, uneven heating and surface marks indicate the lubrication package is not keeping up with line speed.

In elastomers and filled compounds, carbon black and filler dispersion also directly affects torque and dimensional stability.

How PE wax helps

Micronized PE waxes reduce friction, improve mass slip and help disperse fillers. The gain is only sustainable when particle size and softening point are compatible with the thermal cycle.

▸Lower specific torque.
▸More uniform surface finish.
▸Fewer stops due to flow instability.
