Polarity of the substrate dictates the chemical nature of the thermoplastic elastomer and hence the properties and the performance of the thermoplastic elastomer. Figure 1 shows the surface energy match of various thermoplastic elastomers with rigid thermoplastics.

NEUSoft™ Thermoplastics Polyurethanes: a series of ultra-soft TPUs for short-term in-vivo applications. 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 Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility    

Some manufacturers are choosing polymer-metal composites that provide the equivalent weight of metal, but also allow for the design freedom provided by thermoplastics.

Maxxam™ BIO Bio-Based Polyolefin Formulations Maxxam™ BIO polyolefins are formulated with bio-based polyolefin resin and/or 10–50% natural filler from renewable plant sources, including olive seed based powder and cellulose fiber. To satisfy required performance characteristics they can be filled and reinforced with glass fiber, minerals, impact modifiers, colorants and stabilizer systems. KEY CHARACTERISTICS Formulated with bio-based resin and/or 10–50% filler from renewable plant sources, Maxxam BIO formulations: • Reduce product carbon footprint • Achieve equivalent performance to standard polyolefin formulations • Provide good stiffness, durability, impact resistance and UV stability • Deliver good surface finish and are easy to color • Enable customized performance characteristics depending on application need • Offer food contact compliance MARKETS AND APPLICATIONS Maxxam BIO formulations are suitable for use across many industries and applications where traditional polyolefin materials are used, including: • Transportation Interior Applications - Decorative profiles, trunk side liners, pillars, T-cup • Industrial - Structural parts, furniture • Consumer - Household goods, personal care items, packaging, office supplies, food contact applications • Electrical and Electronic – Housings, buttons, junction boxes SUSTAINABILITY BENEFITS • Formulated with bio-based resin and/or 10–50% natural filler • Utilize natural filler from renewable plant sources including olive seed based powder and cellulose fiber • Offer a lower product carbon footprint compared to traditional petroleum-based feedstock • Can be recycled at end of life PRODUCT BULLETIN CHARACTERISTICS UNITS Maxxam BIO MX5200-5036 Natural FD Maxxam BIO MX5200-5030 Natural FD Maxxam BIO MX5200-5030 Natural FD X1 Maxxam BIO MX5200-5001 RS HS Natural Maxxam BIO MX5200-5033 RS HS Natural Maxxam BIO MX5200-5034 RS HS Natural Maxxam BIO MX5200-5035 RS HS Natural Filler/Reinforcement Unfilled Unfilled Unfilled 30% Glass Fiber 10% Mineral 20% Mineral 30% Mineral Density (ISO 1183) g/cm 0.90 0.90 0.90 1.12 0.96 1.03 1.12 Tensile Modulus (ISO 527-1) @ 23°C MPa 1500 1000 1000 6400 1350 1650 2100 Tensile Stress (ISO 527-2) @ 23°C MPa 27.0 20.0 20.0 75.0 13.0 14.0 15.0 Tensile Strain at Break (ISO 527-2) @ 23°C % 5 50 50 3.0 50 37 18 Charpy Notched (ISO 179) kJ/m 5 20 25 10 12 10 10 CHARACTERISTICS UNITS Maxxam BIO MX5200-5023 RS HS HI Natural 70 Maxxam BIO MX5200-5025 RS HS Natural 70 Maxxam BIO MX5200-5004 RS HS Natural 70 Maxxam BIO MX5200-5003 RS Natural 70 Maxxam BIO MX5200-5009 RS HS Natural 70 Maxxam BIO MX5200-5024 RS HS Natural 70 Maxxam BIO MX5200-5022 RS HS Natural 70 Filler/Reinforcement 15% Olive Seed Based 25% Olive Seed Based 30% Olive Seed Based/ 10% Mineral 35% Olive Seed Based/ 5% Mineral 15% Olive Seed Based/ 17% Glass Fiber/ Mineral 20% Olive Seed Based/ 20% Glass/ Mineral 10% Olive Seed Based/ 20% Mineral Density (ISO 1183) g/ccm 1.00 1.15 1.10 1.07 1.09 1.25 1.10 Tensile Modulus (ISO 527-1) @ 23°C MPa 1750 2000 2700 2500 3800 3500 4100 Tensile Stress at Break (ISO 527-2) @ 23°C MPa 21.0 20.0 30.0 20.0 40.0 35.0 42.0 Tensile Strain at Break (ISO 527-2) @ 23°C % 24 5 3 5 3 4 2 Notched Izod (ISO 180) kJ/m 15 7 3 2 5 15 7 MAXXAM BIO POLYOLEFINS – BIO-BASED RESIN – TECHNICAL PERFORMANCE MAXXAM BIO POLYOLEFINS – OLIVE SEED BASED FILLER – TECHNICAL PERFORMANCE CHARACTERISTICS UNITS Maxxam BIO MX5200-5029 NF HI UV Black X1 Maxxam BIO MX5200-5032 NFS UV Natural Maxxam BIO MX5200-5020 NF/NFS UV Natural X1​ Maxxam BIO MX5200-5016 NF Natural Filler/Reinforcement 10% Cellulose Fiber 20% Cellulose Fiber 30% Cellulose Fiber 40% Cellulose Fiber Density (ISO 1183) g/ccm 0.95 1.00 1.02 1.07 Tensile Modulus ISO 527-1) @ 23°C MPa 1550 1750 2640 3600 Tensile Stress at Break (ISO 527-2) @ 23°C MPa 33 30 48 55 Tensile Strain at Break (ISO 527-2) @ 23°C % 8 12 9 4 Charpy Notched Impact Strength (ISO 179/1eA) kJ/m2 5 6 5 5 Charpy Unnotched Impact Strength (ISO 179/1eU) kJ/m2 33 49 38 30 MAXXAM BIO POLYOLEFINS – CELLULOSE FIBER FILLER – TECHNICAL PERFORMANCE Copyright © 2023, Avient Corporation.
