Color, Additives and Inks (CAI) Specialty Engineered Materials (SEM) 1. While conventional air emissions are a critical and a highly- influential topic in some industrial sectors, as a specialty formulator of purchased materials, Avient’s conventional air emission levels from legacy operations are de minimis and not material. Avient does not use PFOA or PFOS in its product formulations.

OnColor™ Color Concentrates for Non-Phtalate PVC Formulations Plasticizers are a major component in PVC formulations. There are different chemistries, including formulations that contain phthalates and non-phthalate plasticizers. Due to the rise in non-phthalate plasticizer demand, Avient offers a range of color concentrates suitable for these formulations.
