Abstract

Apparatus for plasticating a resin polymer, especially polypropylene, includes a barrel (10) having an inlet (14), outlet (18), and inner surface. A screw (22), located within and closely spaced from the inner surface of the barrel, has a longitudinal axis extending from the inlet toward the outlet, and includes length sections arranged in a series along the axis. The screw includes a core (26) and a main flight (24) located on and projecting radially from the core, extending in a helix along the axis, and having a push side and a trailing side. The screw sections include a feed section (42), a transition section (44) following the feed section, a metering section (46) following the transition section, and a barrier melting section (48) following the metering section.
