Abstract
An elastic melt extruder was constructed for extrusion of filler/polymer. Fillers used were glass beads, calcium carbonate powder, glass fiber and carbon fiber. The extrusion was stable for the time duration of practical use.
In the extrusion of filler/polyethylene, the mixing of both components was satisfactory and the filler dispersed uniformly in the extrudate. By assuming instantaneous mixing of the components in the shearing zone of the extruder, theoretical equations for the variation of filler-content in the extrudate with time were derived. The experimental results well reproduced the equations.
