ExxonMobil Introduces New PaxonTM SP5504 HDPE, a Step-Change in Performance for Blow Molded Bottles and Containers
- Published: February 11, 2021
ExxonMobil has developed a new PaxonTM HDPE grade, SP5504, which offers a paradigm shift in the properties normally associated with the currently available unimodal HDPE resins.
Offering a step-change in ESCR (Environmental Stress Cracking Resistance) performance without compromising stiffness, impact, top load performance, or processability, PaxonTM SP5504 is reportedly ideal for household and industrial chemical (HIC) bottles and containers for products like bleach, wipes, and agricultural chemicals.
“Until now, converters have often had to compromise to get the right ESCR performance of blow molded HDPE bottles and containers,” said Dr. James Stern, HDPE business development manager, North America & EMEAF, ExxonMobil. “But, because there is no compromise in density or melt index, PaxonTM SP5504 enables converters to create cost-effective, innovative packaging solutions for household and industrial chemicals.”
In terms of performance, processability and value-based performance, PaxonTM SP5504 fills the space between unimodal and bimodal HDPE grades.
“Because of the superior performance of PaxonTM SP5504, it can be used as a drop-in solution for unimodal HDPE but with a better balance of properties,” added Stern. “Or it can be used to replace bimodal HDPE grades in applications that have had to be over-engineered to obtain a desired balance of ESCR and stiffness.”
PaxonTM SP5504 reportedly enables the production of multiple applications from standard blow molding through to more demanding HIC type applications, plus more complex molded designs can be fabricated with this one material. Brand owners could now be more creative with their packaging designs, while converters could reduce polymer inventories.
With the industry driving towards increased recycling of post-consumer plastic waste (PCR), ExxonMobil has demonstrated value-in-use at PCR levels at and above 25 percent, which may help brand owners and converters to meet changing sustainability targets.
