You can be certain that PolyOne meets or exceeds the material safety data reporting requirements of your country or region. As this program develops, data on negative environmental impacts in the supply chain and actions taken will be included in future reports. Sustainability metrics represent 2018 data or 12-month approximate values based on available data from reporting facilities and are often made in reliance on third-party supplier information.

BENEFITS OF THE CHEMICAL FOAMING PROCESS • Standard equipment compatibility: Maxxam formulations can be processed using standard extrusion equipment, eliminating the need for specialized machinery • Chemical foaming formulation: No investment in gas injection systems or procurement of gas is required • High foaming rates: Achieve up to a 60% foaming rate, optimizing material properties while maintaining performance • Adapted temperature profile: These foamable grades are formulated to work effectively within a tailored temperature profile, offering consistent quality MAXXAM PP COPOLYMERS ARE SPECIALLY FORMULATED TO DELIVER • High-temperature performance: Suitable for applications requiring resistance to elevated temperatures • High foaming rate for cellular formulations: Contributes to better electrical properties due to low density • Excellent mechanical properties: Provides durability and reliability in demanding environments KEY CHARACTERISTICS OF CELLULAR PP FORMULATIONS • Fully formulated PP: no need for other additives • Can be based on chemical foaming agents which are not hazardous substances for a sustainable production process • No need for gas injection • Excellent surface finish and uniform cell structure • Excellent electrical properties to reach stringent capacitance • Low shrinkage • Adapted for skin-foam-skin or foam-skin design • Higher temperature resistance compared to PE • Good crush resistance MARKETS & APPLICATIONS IN WIRE & CABLE • Communication cables such as telecom and data cables • Twisted wire pairs • Coaxial cables

Gel migration is measured using a quantitative internal method * 6151 can be supplied with UV protection * Values concluded from the simulation of materials rheological data and modelling standard extrusion tooling Pressure: can affect extruder performance, higher pressure gives a lower output at the same rpm Shear rate: has a relation with self-cleaning of the walls and mixing conditions Stress: can affect the surface of the product, less stress gives a better surface aspect MIGRATION OF GEL COMPOUND Gel Compound ECCOH™ 6151* ECCOH™ 6153 UV ECCOH™ 6154 UV Unigel Average Good Excellent Teroson Average Excellent Good Itcogel Average Good Excellent ECCOH™ 6151 ECCOH™ 6153 UV ECCOH™ 6154 UV ∆P (bars) 101 63 60 Shear Rate (1/s) 9 9 9 Stress (kPa) 127 79 75 Application example: Gel-filled stranded loose tube optical fiber cable www.avient.com Copyright © 2020, Avient Corporation.
