A mathematical model of the melting of polymeric materials in extruders. Effect of various heat sources on the form and size of the solid plug

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.Translated from Khimicheskie Volokna, No. 4, pp. 49–50, July–August, 1984.
