Avient acquired the Clariant Color business on July 1, 2020 (the “Acquisition Date”). To provide comparable financial results, the Company references “pro forma” financial metrics, which include the business results of Clariant Color for periods prior to the Acquisition Date. It’s in this spirit that we joined legacy PolyOne and the Clariant Color business, two complementary businesses, and formed a new one that we’ve named Avient.

Cesa™ Fiber Additives Flame Retardants for Synthetic Fibers and Nonwovens Ignitability and flame spread, with or without an additional radiant heat source, are a particular concern for fibers used in indoor applications, or indeed anywhere where human lives could be endangered. Our Cesa™ Fiber Additives portfolio includes flame retardant solutions as additive concentrates which are incorporated into the polymer during the spin-dyeing process. APPLICATIONS Cesa Fiber Additives for flame retardancy are recommended for spun-dyed PP, PET and PA fibers used in applications such as automotive textiles, home and office furnishings, clothing, and carpeting.
