Direct machine dosing can provide excellent shot-to-shot consistency and eliminate potential mold plate-out, thus easing processes and control. In some situations the Ultimate UV range can vastly improve both the processing and mechanical properties of packaging incorporating recycled material.

Certain things cannot be controlled by the printer: • The dye in the shirt • The humidity in the air and shirt Things that can be controlled are: • The type of ink – cotton white for cotton, non-ghosting bleed resistant for polyester • The amount of heat used on the garment—cure at the recommended temp, not over • Stack in separate piles to allow cooling—fold in dozens separately, wait to pack Be aware of at-risk colors; brown, tan and beige are the most sensitive to possible ghosting. www.avient.com Copyright © 2020, Avient Corporation.

USE OF NON-GAAP MEASURES PolyOne Corporation 3 • This presentation includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. The non-GAAP financial measures include: adjusted EPS, adjusted operating income, and return on invested capital. • PolyOne’s chief operating decision maker uses these financial measures to monitor and evaluate the ongoing performance of the Company and each business segment and to allocate resources. In addition, operating income before special items and adjusted EPS are components of various PolyOne annual and long-term employee incentive plans. • A reconciliation of each non-GAAP financial measure with the most directly comparable GAAP financial measure is attached to this presentation which is posted on our website at www.polyone.com.

Through accurate and consistent metering, Excelite additives enable greater control of production tolerances and improve linear consistency. This process allows greater control over production tolerances, thus reducing scrap rates, improving quality, and optimizing process capacity.
