Avient acquired the Clariant Masterbatch business (CMB) on July 1, 2020 (the “Acquisition Date”). It’s in this spirit that we joined legacy PolyOne and the Clariant Masterbatch business, two complementary businesses, and formed a new one that we’ve named Avient. We are better together through: Keeping Safety First — PolyOne and Clariant are both ACC Responsible Care® companies, and nothing is more important than the health, safety and well-being of our people.
