Polymer Extrusion

In this experiment, a 27 mm co-rotating intermeshing Leistritz twin screw extruder is used to compound resins containing 20, 30, 40, and 50 wt% calcium carbonate in polypropylene. Then the melt flow index of these resins are determined and compared to that of the pure polypropylene matrix.
