Technical Director for Special Additives Division
The Use of Antioxidants to Improve PCR HDPE Blow Molding
Session 1A - Post-Consumer Resin and Biopolymers
Tuesday, September 13, 2022
2:05 - 2:35 p.m.
(see full conference schedule)
Presentation Description:
High-density polyethylene post-consumer recyclate is being used in a variety of blow molding applications to meet sustainability goals at the consumer, brand owner, and government levels. As the percent PCR inclusion in parts grows, so do the issues associated with the variability of product streams due in part to resin stability. The importance of stabilization will be covered. A series of case studies show how stabilization can improve the blow molding process, as well as the final properties of the blow-molded article will be discussed.
