Plastic Waste 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, including recessionary conditions; 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 polymer consumption growth rates and 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 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 successfully integrate the Avient Protective Materials business and achieve the expected results of the business, including without limitation, the acquisition being accretive; any material adverse changes in the business supporting the Distribution assets being sold; the ability to obtain required regulatory approvals and otherwise consummate the proposed sale of the Distribution business; our ability to achieve the strategic and other objectives relating to the Avient Protective Materials business and the proposed sale of the Distribution business; and other factors described in our Annual Report on Form 10-K for the year ended

In each comparison, polyketone thermoplastics offer product engineers and designers a new tool in the product development toolbox for engineering plastics. A noticeable difference here is impact properties, which are improved for nylons since water plasticizes nylon and makes them more impact resistant.

Sustainability Spotlight Hydrocerol™ Chemical Foaming Agents Reflection electron microscopy (REM) view of foamed plastic Hydrocerol Chemical Foaming Agents are supplied as concentrates CHEMICAL FOAMING AGENTS (CFAs) are chemical substances that react under the influence of heat to release gas into the plastic matrix during the manufacturing process of plastic parts. The gases form a cellular foam structure in the plastic that reduces the amount of material needed and hence the part’s weight. The portfolio includes non-hazardous endothermic substances that require minimum cooling of the plastic parts after manufacturing.

Plastics are renowned for their durability, aesthetics, ease of handling and recyclability. The 2021 average injury incidence rate for our NAICS Code (326 Plastics and Rubber Products Manufacturing) was 3.40. In addition, we continue to engage and invest in the Alliance to End Plastic Waste (AEPW).

Plastics In many ways, plastics are a perfect example of why a circular economy is so important. If not recycled properly, plastics can ends up in a landfill or, even worse, the ocean. Efforts can be made and systems can be built to keep discarded plastic in the economy to either be upcycled, recycled, reused or composted.
