Following are top reasons why many manufacturers and designers choose high-performance thermoplastics: • High-temperature resistance • Chemical resistance • Flame/smoke/toxicity (FST) performance • Chemically inert PLUS, ALL THE BENEFITS OF PLASTIC In addition to their elite-level properties, high-performance thermoplastics deliver the typical advantages of polymers over other material types such as metal, glass and ceramic, including: • Light weight • Design freedom/part consolidation • Easy colorability • Efficient, high-volume processing • Elimination of secondary operations • Enhanced product experience for the end user - quieter environment - improved tactile feel - better usability ADVANTAGES Going Above and Beyond • Amorphous structure • High marks for toughness, chemical resistance, hydrolytic stability, resistance to boiling water, and extreme thermal capabilities • Best for: aerospace interiors, hot water fittings, and medical and dental devices that are subjected to repeated steam sterilization • Also used in food equipment exposed to temperature extremes, such as coffeemakers or freezer-to-microwave cookware Polyaryletherketones Polysulfones Liquid crystal polymers Polyetherimides Polyphenylene sulfides There are five major families of high-performance thermoplastics AR YL ET H KE TO N ES SU LF O N ES• Semi-crystalline structure • High marks for thermal stability, chemical resistance and mechanical properties over a wide temperature range • Better-than-average levels of combustion resistance and electrical performance • Some PAEK materials, like polyetheretherketone (PEEK), are also extremely tough and have excellent impact strength • Best for: aerospace, automotive, industrial and medical components • May be used to create stock shapes such as rods, bars, and tubes All in the Family PH EN YL EN E SU LF ES • Semi-crystalline structure • Excellent temperature resistance with continuous service temperatures up to 230°C • High marks for modulus and resistance to creep, corrosion, and chemicals • Above-average electrical properties • Best for: complex parts with extremely tight tolerances; often used as an alternative to metals and thermosets in automotive underhood parts, appliances, electronics, and industrial applications Polyaryletherketones Polysulfones Liquid crystal polymers Polyetherimides Polyphenylene sulfides There are five major families of high-performance thermoplastics ET H IM ES LI Q U C RY ST AL P O M S • Semi-crystalline structure • High degree of anisotropy: strength, stiffness and thermal expansion will be greater in one direction vs. the other • High marks for temperature, chemical and electrical resistance • Exceptional mechanical strength and high flow rates; often used to fill extremely long parts with thin walls • Best for: electronic connectors, sensors, bullet-resistant vests, jet engine enclosures, brake and transmission friction parts, and gaskets • Amorphous structure • High marks for thermal, mechanical, and chemical properties • Often selected for demanding applications requiring ultra-high mechanical strength combined with high temperature, corrosion and wear resistance • Impact resistance may be lower than that of PSUs and PAEKs • Best for: aerospace interiors, automotive lighting, medical devices, and electrical and fiber optic connectors All in the Family Source: https://www.craftechind.com/standard-and-custom-parts-in-high-performance-plastics/ TEMPERATURE AND MATERIAL TYPE The two broad classifications of high-performance thermoplastics—amorphous and semi-crystalline— have different temperature characteristics.

Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior period s 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.

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; disruptions or inefficiencies in our supply chain, logistics, or operations; changes in laws and regulations in jurisdictions where we conduct business, including with respect to plastics and climate change; fluctuations in raw material prices, quality and supply, and in energy prices and supply; demand for our products and services; 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 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; our ability to achieve strategic objectives and successfully integrate acquisitions, including the implementation of a cloud-based enterprise resource planning system, S/4HANA; 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, geopolitical conflicts and any recessionary conditions.
