Post-extrusion mixing device ensures good color and additive distribution and uniform temperatures over a range of thermoplastics, including nylons, polyethylenes, styrenes, acrylics, cellulosics and vinyl resins. Chemineer Kenics thermogenizer uses a stationary, helical Kenics static mixer element assembly. It induces flow divisions in the melt stream. Flow splitting and axial rotation of the stream help ensure continuous transfer of material between the wall and the center of the stream. The melt-stream heating system can be supplied with electrical band heaters and thermocouple ports for wall temperature control. Available in 1, 1.5, 2, 3 and 4” diameters, the thermogenizers install between the exit of an extruder and the accompanying die.
