Underlying organic sales growth plus the addition of Magenta's fiber colorant business and Kraton's TPE business was more than offset by lower year-over-year selling prices in Distribution, PP&S, and Designed Structures and Solutions (DSS), due to lower hydro-carbon based raw material costs. They are based on management's expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements.

Luxury Toothbrush Base Gravi-Tech™  replaces metal and maintains performance for luxury toothbrush base OnColor™ Bio Colorants offered bio-based colorants to support carbon footprint reduction for smartwatch housing

They are based on management's expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. Stock based compensation expense Senior management uses gross margin before special items, operating income before special items and free cash flow to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and that current levels may serve as a base for future performance.

Gravi-Tech™ Density Modified Formulations PROCESSING GUIDE 2 Gravi-Tech GRAVI-TECH™ Density Modified Formulations Gravi-Tech™ polymer-metal composites are high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. Gate type should be selected based on location and part geometry. 2. Place these wells at the base of the sprue to capture the cold material first emerging from the nozzle. 2.

Working closely with the manufacturer’s engineers, Avient determined that the material required a special combination of properties: • A heat-resistant base resin that would provide the level of signal dampening prescribed • Mechanical properties that would ensure an effective electrical connection and at the same time allow for snap-fit installation • A cost-effective solution that would enable the manufacturer to compete in this new market Striving for optimal results, the manufacturer evaluated more than 30 different materials. THE IMPACT Avient’s solution was a unique, nylon-based material that met the all of the application’s performance requirements.

PREPERM technology enables a high degree of customization based on individual customer needs. The advantages of PREPERM materials relate to more efficient data transfer (antennas, mobile base stations, satellite communication), better sensitivity (GPS, radars, radomes) and longer battery life (mobile and IoT devices).

IARC’s listing of carbon black as a Group 2B carcinogen is based on laboratory rat studies only; studies on carbon black production workers have not shown a link between carbon black exposure and cancer. COMPANY CONTACT INFORMATION corporateregulatory@avient.com ENVIRONMENTAL EFFECTS Based on its physical/ chemical properties (insolubility, no vapor pressure), Carbon Black released into the environment will be distributed mainly in soil or sediments.

As a result of these plastisol aging characteristics and the potential differences in testing methodology, it is strongly recommended that incoming quality control (QC) specifications not be established based on plastisol Technical Data Sheets (TDS), or Certificates of Analysis (COA). QC specifications should be based on the needs of the process and end product.
