Beggs continued, “In the first quarter, we expect to experience similar demand conditions as in the fourth quarter of 2022, driven by negative consumer sentiment, rising interest rates and a slow restart of China. Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; the current and potential future impact of the COVID-19 pandemic on our business, results of operations, financial position or cash flows including, without limitation, any supply chain and logistics issues; changes in laws and regulations regarding plastics in jurisdictions where we conduct business; fluctuations in raw material prices, quality and supply, and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; our ability to achieve strategic objectives and successfully integrate acquisitions, including Avient Protective Materials; an inability to raise or sustain prices for products or services; our ability to pay regular quarterly cash dividends and the amounts and timing of any future dividends; information systems failures and cyberattacks; amounts for cash and non-cash charges related to restructuring plans that may differ from original estimates, including because of timing changes associated with the underlying actions; and other factors affecting our business beyond our control, including without limitation, changes in the general economy, changes in interest rates, changes in the rate of inflation and any recessionary conditions.

Melt processing of ColorMatrix AAzure products is carried out at typical PET processing conditions at recommended dose rates, which range from 0.01% to 0.13%. Care must be taken to optimize the bottle blowing process due to the increased heat- up rate of the preform, to take advantage of the many benefits offered by this product range.

PRODUCT BULLETIN EXCELITE - COMMON FORMULATIONS USAGE RATES Typically Excelite additives are dosed between 0.2% and 1.2% depending on the polymer, application and the density requirement. PRODUCTS APPLICATIONS DESCRIPTION/BENEFITS EXCELITE PF-1 PVC sheet for digital print or trimboard; profiles & decking Fine cell structure able to target low density: improves consistency and control over foaming process FOAM ADDITIVE-54 PVC sheet for digital print or trimboard; profiles & decking Finer cell structure than PF-1 promotes ultra smooth surface finish; improves consistency and control over foaming process PF-1E & FA-54E ADDITIVES PVC sheet for digital print or trimboard; profiles & decking Enhanced run time formulation reduces die lip build-up in PVC processes, leading to longer production run times FOAM ADDITIVE-33 CaZN formulations for PVC sheet, profile, or trimboard Promotes finer cell structure, higher cell density, and surface quality in CaZN PVC dryblends FOAM ADDITIVE-77 HDPE sheet & plastic lumber Industry-leading cell structure and cell density; achieves lower density without sacrificing quality; self-nucleating and able to increase extruder output rates up to 15% FOAM ADDITIVE-85 Endothermic foam or nucleating additive for olefin and styrene polymers; plastic lumber, sheet applications and food packaging products Can be used as a CFA or nucleating additive; nucleating capabilities promote fine cell structure and high cell density; achieves greater density reductions with more consistency and control FOAM ADDITIVE-37 HDPE sheet & plastic lumber Good cell structure and cell density in HDPE lumber; greater consistency and control over foaming process EXCELITE CAN IMPROVE PRODUCTION EFFICIENCY • The process operator has full control of density • Minimizes product rejection due to unnecessarily high/low density • Production should consistently target the bottom of the density specification • Enables control over the reintroduction of regrind or reprocessed materials as a feedstock • Enables the consistent foaming of products using higher percentages of regrind • Carrier selection can promote longer run times, enabling increased line productivity through less plate-out or material build-up on die lips EXCELITE CAN IMPROVE SURFACE FINISH Excelite additives creates a fine, consistent cell structure within the extruded polymer, which determine the surface roughness. This process allows greater control over production tolerances, thus reducing scrap rates, improving quality, and optimizing process capacity.
