Mixing Screws Versus Non-Mixing Screws, Part II: The Results, 1998 Polymers, Laminations & Coatings Conference Proceedings

Data indicate that mixing screws better disperse dissimilar materials, e.g., inorganic additives in polymers, than do non-mixing screws. However, mixing screws, unlike non-mixing screws, significantly change an extruded polymer’s morphological properties from those of the original pellets. One must therefore weigh significant changes in polymer properties versus the better dispersion effected by a mixing screw. Finally, if one is extruding a pre-blended, or straight reactor polymer, a non-mixing screw is probably the preferred choice of screws.
