PRODUCT BULLETIN Non-PFAS Polymer Process Aids for Extrusion in Polyolefins Cesa™ and Hiformer™ Non-PFAS Process Aids are formulated without the use of fluorochemicals. These non- PFAS processing aids can be tailored to any carrier. WHY NON-PFAS PROCESSING AIDS?

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.

Utility  — Traditional wood and metal utility poles and cross arms are increasingly being replaced by polymer composites because they are non-conductive, durable, and lighter weight than wood or steel, which makes them easier to install. In all cases, polymer composites enhance performance thanks to their resistance to corrosion, heat, weather, and flame.

The non-GAAP financial measures include: Adjusted Earnings Per Share, Net Debt / Adjusted EBITDA, and Adjusted EBITDA. EBITDA and Adjusted EBITDA are non-GAAP financial measures that management uses in evaluating operating performance. The presentation of these measures may be different from non-GAAP financial measures used by other companies.
