38 39Avient CORPORATION • Inconsistent base color of recycled materials • Lightest color recycled material in high demand for all applications ($$) • Even with clear/transparent materials, color degrades over repeated processing • OpticaTM Toners and Super-concentrated colorants to reduce and mask recycled material discoloration • SmartHeatTM reduces heat history to minimize yellowing • Color Simulation Tool to assist with color space design • Stabilization of color fluctuation driven by variable recycled polymer • In-line color correction to optimize customer manufacturing efficiency RECYCLE COLOR QUALITY RANGE Avient Corporation 39 1: Color Management Recycled Material Restricts Color Options With virgin material, we can design across a broad color spectrum The darker the recycled materials, the more color design freedom is restricted This bright yellow is not achievable with high concentrations of dark recycled materials Avient can provide customer guidance on maximum recycle content possible and color concentration required to achieve desired color Avient Corporation 40 Case Study with Brand Owner Recycled Resin = Discolored Base Virgin Resin = Clean Color Base

T A N D A D D I T I V E S Avient Corporation 42 $100M + 2: Decontamination Recycled material feedstocks are contaminated • Feedstock variability supplies the recycle process • Insufficient washing at recycler • Residual labels and printing inks cause quality and NIAS issues • Unpleasant recycled material odor (in processing and the final application) • Clean, food grade, recycled material availability in high demand • Reliable decontamination to reduce NIAS concerns • Full odor removal • CESATM Laser Marking to eliminate contaminating printing inks, labels and glue • AAzureTM process aids and scavengers to enable food and beverage taste purity in PET packaging • ProsureTM range of formulations to enable NIAS compliance and security (customer peace of mind) NIAS = Non Intentionally Added Substances Avient Corporation 43 44 3: Maintaining Mechanical Properties • Mechanical properties of recycled materials degrade after multiple heat cycles • Today's recycling protocols only focus on one recycle loop…in reality, there will be several • Legislation and brand owners are targeting higher recycled material ratio incorporation and full circularity • Polymer quality stability over multiple loops to deliver circular recyclability • Stress cracking of recycled bottles • Upgrading performance of lower quality recycled materials • Specification and guided selection amongst highly variable recycled materials • CESATM antioxidants and process aids to enhance physical properties • SmartHeatTM reduces heat history to minimize yellowing • rePrize™ for PET polymer chain repair and extension Avient Corporation 44 Multi-material packaging is harder to recycle • Contamination of polymer streams • Issues in sorting • Issues in separation • Trend is to restrict multi-material systems in favor of mono-material constructions • Improve recyclability of PET gas barriers • Barrier system development for Polyolefins • Recyclable barrier systems for film and sheet • Portfolio of compatibilizers to enable multilayer constructions • AmosorbTM to extend beverage shelf life by scavenging oxygen through the bottle wall • CaptureTM to extend product shelf life through oxygen scavenging but without contaminating the bottle • Lactra SX TM to prevent light-induced oxidation in liquid dairy products stored at higher temperatures Avient Corporation 45 4: Mono-Material Construction 46 Brand Owners require a consistent brand identity • Inconsistent quality streams pose a challenge to delivering homogeneous product quality and aesthetics to the consumer • Brands demand recycled content, but with color/property consistency • Recyclers are challenged to fulfill needs from brand owners and convertors • Specification and selection of recycled material grades for targeted applications • Simulation of recycled material performance in the end-use application • Leverage re-formulation expertise to provide a consistent packaging product (color and mechanical properties) Our Service and Color Expertise differentiate Avient and allow us to support customers throughout the entire design process • Design for use: Color matching, Color design options • Recycle
