CLEVELAND – April 30, 2021 – Avient Corporation (NYSE: AVNT), a leading provider of specialized and sustainable material solutions, today reported its first quarter results for 2021. The Specialty Engineered Materials segment also achieved its highest-ever quarterly operating income at $34 million, a 53% increase over the prior year. Examples include: • Barrier technologies that preserve the shelf-life and quality of food, beverages, medicine and other perishable goods through high-performance materials that require less plastic • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation • Breakthrough technologies that minimize wastewater and improve the recyclability of materials and packaging across a spectrum of end uses Avient employs approximately 8,400 associates and is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.

These high-performing materials deliver high- temperature performance, mechanical integrity, and excellent impact resistance for demanding engine applications. These robust materials also incorporate heat stabilization to maintain tensile strength and tensile elongation properties for long- term thermal aging up to 120°C. Processing conditions can cause material properties to shift from the values stated in the information.

A challenge faced when coloring PCR resins include recyclate materials with an undertone or opacity that can restrict color options in PET, rPET and rPP. Lightest colored recycled materials are therefore in high demand for all applications, limiting market availability. Processing conditions can cause material properties to shift from the values stated in the information.

Density is measured in grams per cubic centimeters (g/cc) with every 0.01 g/cc reduction resulting in less material used. A decrease in density of just 0.01–0.02 g/cc can yield 4% annual savings in material consumption, while generating a 4% increase in extruder productivity. For example, in several instances processors ran Excelite E-versions, which allowed longer production run times and less material plate-out on extruder die lips.

OEMs and tier-one suppliers strive to reduce vehicle weight and incorporate more recycled materials into parts. Plus, they can support OEMs in complying with the ELV Directive targets for incorporating recycled materials. Processing conditions can cause material properties to shift from the values stated in the information.
