Stabilization of PE for rPE Applications: Pre or Post-stabilization?
A challenging goal of PE mechanical recycling is to maximize the inclusion of recycled content while maintaining the physical properties and aesthetic performance of the extruded article. There are two approaches that the industry has adopted: improve virgin resin recyclability via enhanced stabilization (proactive) or the addition of supplemental stabilization during the rPE recompounding stage (reactive). Both approaches have been proven to be effective, however; there are no studies reported to date that compare the effectiveness of each approach. In this study, we evaluate the proactive and reactive approaches using a general purpose blown film LLDPE resin. The results of the study indicate that incorporating pre-stabilization improves the quality of the rPE compared to post-stabilization. Further, the use of more advanced stabilization technologies not only improves the recyclability of the virgin PE resin but also enables the finished article to incorporate more recycled content.

New Additive Technology to Improve the Chlorine Resistance of Potable HDPE Pipe
A new high performance stabilizer solution has been developed for use in HDPE, especially for pipe where exposure to chlorine is anticipated. Chlorine-based disinfectants are known to be extremely effective in eliminating waterborne pathogens in potable water systems but can also contribute to pipe deterioration. Chlorine disinfectants also interfere with stabilizer additive packages which provide pipe longevity. This new plastic additive technology enables HDPE pipes to be used in contact with chlorinated water estimated to have service life-time of more than 50 years. The new technology meets current drinking water regulations and reduces the migration of non-intentionally added substances, NIAS, including Arvin substances.

Developing Novel Stabilizers with Optimized Performance for PP in Automotive Application
Design of experiments (DOE) is a powerful tool that harnesses applied statistics to gain insights into a variety of processes and formulations. In this study, DOE was used to investigate polymer additive formulations in polypropylene undergoing long-term thermal aging under ASTM D3012. Three components and one interaction between components were found to drive thermal aging performance. A mathematical model was developed from the experiments to predict cost-optimized formulas for a given performance level, leading to new product developments.
