Studying single-pass degradation of a high-density polyethylene in an injection molding process
Abstract
This paper explores the potential for degradation of a Ziegler–Natta polymerized high-density polyethylene (HDPE) that may result from single-pass processing through a 55-tonne injection molding machine. The conducted experiments examined the influence of processing temperature (190–270°C), shear rate (4000–7500s−1), type of antioxidant, and concentration of antioxidant, on changes to the polymer structure. The extent of degradation was …
