AVIENT ADVANCED COMPOSITES OVERVIEW LOWER ENERGY COSTS Requires less energy during installation and use INCREASE COMPETITIVE ADVANTAGE Customizable solutions for specific application needs REDUCE PRODUCT LIFECYCLE COSTS Lower installation time, as well as warranty and �part replacement � expenses EXTEND PRODUCT LIFETIME Corrosion, flame, fatigue and UV resistant for improved durability DESIGN STRONG, LIGHTER WEIGHT COMPONENTS Up to 75% lighter than steel and up to 25% lighter than aluminum ADVANCED COMPOSITES An exceptional alternative to traditional materials such as wood, ceramic and metal, advanced composite solutions enable designers to: • Design lighter weight structural components for increased lifetime performance and improved fuel efficiency—higher strength-to-weight ratios to exceed the structural performance of traditional materials while significantly reducing weight—up to 75% lighter than steel and up to 25% lighter than aluminum • Extend product lifetime to reduce part replacement and decrease warranty expenses— the corrosion, weather, flame and fatigue resistance of composite solutions improve component durability • Reduce product lifecycle costs—the extended product lifetime, along with the potential for reduced installation time and cost due to the lighter weight of composite solutions, significantly reduces the associated cost over the lifetime of a part • Lower energy costs—by leveraging a higher strength-to-weight ratio, composite solutions allow designers to engineer products that require less energy or power during installation and use • Increase competitive advantage—Avient advanced composite solutions can be customized to provide electrical insulation, thermal insulation, radiopacity, low thermal expansion, flexural memory and load damping, while delivering desired performance and aesthetic specifications TRANSPORTATION Truck floors, liners and aerodynamic components, rail car doors and panels, automotive structural solutions, leaf springs, traffic safety markers and delineators, air cargo unit load devices (ULDs) The Avient advanced composites portfolio offers customized solutions to serve a full range of markets and industries, including: USES & APPLICATIONS ENERGY Wind turbine blade stiffening components, sucker rods, oil & gas production solutions BUILDING & CONSTRUCTION Structural blast protection, garage doors, modular construction, temporary shelters, architectural columns, concrete and masonry reinforcements, pipe reinforcement HEALTHCARE External orthopedic fixators, endoscopy wands, prosthetics MARINE Panels for decking, bulkheads, cabinets, doors, transoms, ceilings; reinforcements for stringers; sail battens CONSUMER & RECREATION Archery bow limbs and risers, furniture springs, diving board springs, golf flagpoles, snowsports equipment, sporting stick shafts, paddle shafts, lightweight and extendable mast structures ELECTRICAL & TELECOMMUNICATIONS Utility poles and cross-arms, high voltage transmission & distribution insulator cores, surge arresters, bus bar covers and electrical tool components INDUSTRIAL Pallet stiffeners, pipe reinforcement, conveyor springs, dock shelters PROCESSES & CAPABILITIES Avient’s reinforced composite technologies use carbon, glass and aramid fibers with custom formulated thermoset or thermoplastic resins in continuous forming processes.

This includes masks, protective garments, medical tubing and packaging for personal care products. OnFlex™ LO Low VOC/ Fog Thermoplastic Elastomers OnColor™ FX Special Effect Colorants Human Health & Safety Solutions that directly protect and preserve human health (e.g., Hygiene & Personal Protective Equipment (PPE) and medical devices) Mevopur™ Polyolefin-based Formulations and Masterbatches Versaflex™ HC Thermoplastic Elastomers Contains Recycle Content: Incorporates post-consumer or post-industrial recycle content. Versaflex™ HC Thermoplastic Elastomers are formulated to meet demanding healthcare device and application challenges without phthalate plasticizers.

Additionally, long fiber composites retain a significant amount of their durability at low and elevated temperatures making them desirable for devices exposed to varying climates. Inclusion of additional additives into long fiber composites can render molded articles radiopaque for medical diagnostic procedures.
