Abstract
The high potential of layered silicate improving material properties of plastics has been discussed in a significant number of publications. However, homogeneously dispersing it with twin screw extruders is demanding. Available information on optimum screw configuration is contradictory. In this investigation, we develop a practical method for individually designing and optimising extruder sections. This method is applied for designing extruder sections for compounding masterbatches of high-density polyethylene and layered silicate. We found out that for best dispersion, dispersing sections should only be partially filled with melt. Thus, only right-handed kneading elements should be applied.
