It is specially formulated for polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET), and Nylon.  Avient and Coloro are working together to explore more solutions and applications in the textile industry to help brands reduce waste and emissions while providing more sustainable color choices. Dyneema®, the world’s strongest fiber™, enables unmatched levels of performance and protection for end-use applications, including ballistic personal protection, marine and sustainable infrastructure and outdoor sports  

Co-Create: Customizing Your Product During the second phase, the brand owner and the plastics processor work together to develop customized solutions for the specific needs of the application. HiFormer™ liquid masterbatch technology can help brand owners and plastic converters optimize the coloration of plastics used in applications ranging from personal care, food and beverage, appliances to construction and toys See how our specially formulated colorants can help differentiate your brand

OnColor™ UL 94 colorants* for Electrical & Electronic (E&E) applications allow fast, cost-efficient project management combined with all the advantages of in-house coloration. Compliance to IEC 60695 part 2-11 for the end product and parts 2-12 and 2-13 for materials is required in Europe—and increasingly in other regions—for certain electrical and electronic applications. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.

GLOBAL ELECTRICAL EQUIPMENT PROVIDER S W I T C H G E A R P L U N G E R • Customer looking to replace metal. Material needs to: • Pass ampere test at 10A and 16A conditions • Pass glow wire test at 750°C at 1.5mm thickness • Have a lubrication effect and dimensional stability at an elevated temperature of 110°C • Meet test criteria of 250K cycles switch on/off without failure or dimensional changes • Reduced risk of shock by replacing brass with polymer formulation that met all key electrical and functional performance criteria • Eliminated the need for secondary lubricant due to self- lubricating properties of LubriOne materials • Enabled in-house molding which removed reliance on external part supplier and allowed direct management of global inventory levels LubriOne™ Internally Lubricated Formulations KEY REQUIREMENTS WHY AVIENT? https://www.polyone.com/products/engineered-polymer-formulations/general-engineered-formulations/lubrione-internally

Key Features • High Strength & Modulus • Corrosion resistant • Electrical & thermal conductor • Flame Resistant • UV Inert • X-Ray Permeable • Excellent EMI (Electromagnetic Interference) Disadvantages • Susceptible to filamentation • Conductivity may be a hindrance to some processing • Susceptible to galvanic corrosion • Poor abrasion resistance (untreated) FIBER-LINE® PROCESS FOR CARBON FIBER • Coating • Twisting • Extrusion • Pultrusion • Precision Winding FIBER-LINE® CARBON FIBER PRODUCTS • Strength Members • Packing Yarn • Belt & Hose Reinforcement Yarn • Synthetic Wire Rope WHY CARBON FIBER? Traditionally, Carbon fiber tows were used in thermoset composite applications but are being incorporated into thermoplastics more and more. Typically, higher carbon purity yields greater conductive and modulus properties but in turn produces a less flexible and stiff tow.

absent registration or an applicable exemption from registration requirements. 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; disruptions or inefficiencies in our supply chain, logistics, or operations; changes in laws and regulations in jurisdictions where we conduct business, including with respect to plastics and climate change; fluctuations in raw material prices, quality and supply, and in energy prices and supply; demand for our products and services; 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 achieve strategic objectives and successfully integrate acquisitions, including the implementation of a cloud-based enterprise resource planning system, S/4HANA; 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, geopolitical conflicts, and any recessionary conditions; and other factors described in our Annual Report on Form 10-K for the year ended

It is an annual trend forecasting tool that focuses on the color and effects of plastics used in packaging, consumer products, automotive applications, and synthetic fibers. The first step in the ColorForward process is to conduct extensive research on the societal trends that are expected to be prominent worldwide and their impact on consumers’ aesthetic preferences.
