Maxxam™ REC Recycled Polyolefin Formulations Maxxam™ REC Recycled Polyolefins are formulated with 25–100% recycled resin from post-industrial recycled (PIR) and post-consumer recycled (PCR) sources. Maxxam REC Polyolefins can be fully customized to meet specific application needs. KEY CHARACTERISTICS • Formulated with 25–100% recycled resin from PIR & PCR sources • Reduces waste and supports the circular economy • Achieves equivalent performance to standard polyolefin formulations • Can be recycled at end of life • Provides good stiffness, durability, impact resistance and UV stability • Enables customized performance characteristics depending on application need MARKETS AND APPLICATIONS Maxxam REC Polyolefins are suitable for use across many industries and applications where traditional polyolefin materials are used, including: • Transportation - HVAC systems, engine guards, battery housings, flame retardant applications • Industrial - Structural parts, furniture • Consumer - Household appliances, personal care items, packaging, office supplies, food contact applications • Electrical and Electronic – Housings, buttons, junction boxes SUSTAINABILITY BENEFITS • Formulated with 25–100% recycled resin from PIR and/or PCR sources • Reduces waste and supports the circular economy • Reduces carbon footprint • Can be recycled at end of life PRODUCT BULLETIN CHARACTERISTICS UNITS Maxxam REC RS5200-5029 C BLACK X2 Maxxam REC MX5200-5036 HS I BLACK Maxxam REC MX5200-5037 Maxxam REC MX5200-5038 Maxxam REC MX5200-5039 Filler/ Reinforcement – Unfilled Unfilled 20% Mineral 40% Mineral 30% Glass Fiber Recycled Content – 95% PCR 97% PIR 75% PIR 55% PIR 65% PIR Density (ISO 1183) g/ccm 0.93 0.95 1.09 1.28 1.15 Tensile Modulus (ISO 527-1) MPa 1250 950 1500 2150 4250 Tensile Stress (ISO 527-2) MPa 25 175 10 15 50 Tensile Strain Break (ISO 527-2) % >20 >80 >30 17 4.5 Charpy Notched (ISO 179) kJ/m 3 8 5 4 11 TECHNICAL PERFORMANCE CHARACTERISTICS UNITS Maxxam REC RS5200-5026 RS NHFR BLACK 70 Maxxam REC FR H8 V2 BLACK RG 70 Maxxam REC L6 GF/30 H BLACK T RG 70 Maxxam REC MX5200-5027 RS HS BLACK RG Maxxam REC MX5200-5028 RS HS BLACK RG Maxxam REC C10 H-UV AS EP RG BLACK 70 Filler/ Reinforcement – 30% Glass Fiber Unfilled 30% Glass Fiber 30% Glass Fiber 40% Talcum Unfilled Recycled Content – 37% PIR 90% PIR 55% PIR 35% PIR 50% PIR 25% PIR Density (ISO 1183) g/ccm 1.42 0.950 1.13 1.15 1.23 1.03 Tensile Modulus (ISO 527-1) MPa 8250 1300 6100 6400 – 700 Tensile Stress (ISO 527-2) MPa 71.0 30.0 70.0 70.0 28.0 15.0 Notched Izod (ISO 180) kJ/m – 4.0 10 5.8 2.7 No Break Flame Rating @ 1.6mm thickness (UL 94) – V-0 V-2 HB HB HB HB TECHNICAL PERFORMANCE Copyright © 2023, Avient Corporation.

Airtight housings are molded from Maxxam™ FR non-halogenated flame retardant polymers and overmolded with OnFlex™ non-halogenated, flame-retardant thermoplastic elastomers (TPEs). In addition to its non-halogen formulation, the regulatory-compliant Maxxam solution has a lower density than traditional materials, which reduces material consumption and housing weight for greater production efficiency.
