Abstract
A single extruder screw is presented which includes a plurality of equidistant undercut barriers disposed in a preselected pattern within the channel of an extrusion screw. The undercut barriers are disposed in the first metering stage and second metering stage and provide increased dispersive and distributed mixing for highly viscous difficult to blend materials. In another embodiment the single extruder includes a slotted blister ring, having slots and lands disposed thereon, positioned between the first metering stage and the vent zone to further increase the amount of mixing.
