Shear Rate Dependence Shear rate’ is proportional to the speed or flow rate that a TPE is moving against the wall of the tool. Due to this unique viscosity/shear rate dependency, normal melt index testing (done at shear rates as low as 50 1/sec) will not reflect how the TPE will process at higher shear rates.

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; 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 achieve the strategic and other objectives relating to the Avient Protective Materials business; 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.
