Conclusions
The form and size of the solid polymer plug in melting polymeric materials in plasticizing extruders depend on the source of heat: external, dissipation of mechanical energy, or preliminary warming of the flake.
The length of the polymer melting zone is determined by the rate of rotation of the extruder screw.
