Low molecular weight polyethylene based on metallocene technology was first commercialized in the world in 2004 as a functional additive by Mitsui Chemicals, INC. We found many advantages for polymer processing, these are increase output, save energy consumption, reduce die build-up and scorching using the new additive without any side effect on products quality. In this work, the improvement mechanisms of polymer processing properties were investigated quantitatively by means of single screw extruder experiments and rheological analyses. Effect of wall slip is dominant for improve the extrusion property.
