PES / PSU / PPSU Colorants
https://www.avient.com/news/avient-launches-two-new-sustainable-polymer-solutions-medical-and-pharmaceutical-applications-during-pharmapack-europe-2021
New at Pharmapack are color and additive masterbatches based on a PE carrier that is manufactured using non-fossil feedstocks.
MEVOPUR pre-colored formulations based on bio-derived PE are also being introduced today for customers who prefer ready-to-use solutions.
https://www.avient.com/sites/default/files/2020-10/tpe-injection-molding-guide.pdf
Most Versaflex™, Dynaflex™ and OnFlex™ materials (and Versalloy™ TPV alloys) are
suitable for two-shot or insert molding onto a PP (and in some cases, PE) substrate.
Dry colors have also been used but may require more material
and time to perform color changes.

The use of a polyethylene (PE) carrier may adversely effect adhesion to the substrate for
some overmolding applications.
