Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. In addition, operating income before the effect of special items is a component of Avient's annual incentive plans and is used in debt covenant computations.

These characteristics offer manufacturers a high-performing, cost-effective and more eco-conscious alternative to nylon (PA66 and PA6) and acetal (POM). KEY CHARACTERISTICS • Inherently low COF • Excellent wear resistance • Excellent chemical resistance • Low moisture uptake • Excellent dimensional stability • Cost-effective • Eco-conscious alternative to PA66, PA6 and POM MARKETS & APPLICATIONS These materials are ideal for use in applications requiring lubricated solutions, as the formulations have improved wear, chemical, and hydrolysis resistance over nylons (PA6 or PA66).

Organic antimicrobials consist of substances that migrate within the polymer matrix, spreading over the surface of the materials where their antimicrobial action has effect. Organic antimicrobials are effective at low concentrations, offering a favorable cost/performance ratio in polymers that are processed at temperatures not exceeding 250°C (482°F).
