They also offer over 2x higher impact properties than short fiber reinforced solutions, while maintaining impact properties in cold and demanding environments. KEY CHARACTERISTICS • Chemical resistance • Maintaining high impact performance at low temperatures • Low moisture uptake • Dimensional stability comparable to nylon • Higher impact resistance than short fiber alternatives • Eco-conscious alternative to nylons • More cost-effective solution than specialty nylons • Available in non-PFAS* formulations to achieve UL 94 V-0 flame rating at 1.5 mm MARKETS & APPLICATIONS These materials are for use in applications traditionally made of metal requiring moisture, chemical and cold impact performance requirements, including: • Industrial – pipes, tubing, fluid management • Electrical & Electronics – connectors, battery components, battery housings • Transportation – under-the-hood fuel/ chemical contact components, non-structural interior components • Oil & Gas – fuel pump components, fuel doors PRODUCT BULLETIN * Non-PFAS flame-retardant (FR) grades are manufactured without intentionally added PFAS-based raw materials. ■ Notched 23C ■ Unnotched 23C ■ Unnotched -30C■ Notched -30C 0 5 10 15 20 25 Complēt LGF30-PKE NAT Complēt LGF40-PKE NAT Complēt LGF50-PKE NAT Izod Impact Notched ASTM D256/Unnotched ASTM D4812 4.1 4.7 5.4 18.9 19.5 19.919.1 19.8 20.1 4.0 4.6 5.0 (1) Data based on single lot of lab generated samples.

During injection molding, longer fibers align and intertwine to form an internal skeletal network, enabling a unique set of performance characteristics, including: • High strength-to-weight ratio which facilitates metal replacement to achieve weight reduction • Added stiffness and strength to carry loads while resisting creep deformation • Increased toughness to absorb impact forces without permanent damage • High cyclical fatigue endurance to resist cracking and crack propagation • Mechanical performance that is retained across a wide temperature range • Improved dimensional stability with nearly isotropic properties and low thermal expansion • Corrosion and chemical resistance Long fiber composites provide a combination of stiffness, strength, and toughness performance enhancements not available together when using other reinforcing methods, while retaining the single- step processing simplicity of injection molding. Complēt™ MT Maximum toughness, long fiber reinforced nylons (polyamides) formulated for extra impact and fatigue resistance. OVERCOME MATERIAL CHALLENGES Deploy long fiber reinforced composites to meet these needs: • Metal replacement for weight reduction • Failure of lower performing plastics • Structural load carrying requirements • Increased impact or fatigue durability • Wide temperature range performance • Thermoplastic design freedom • Manufacturing process cost savings 1.844.4AVIENT www.avient.com Copyright © 2024, Avient Corporation.

Polyamide (i.e. nylon) is preferred plastic in many high end applications due to its crystalline structure and high melting temperature. The viscosity is in the lower end of the spectrum as shown in the figure 2 in high shear rate regimes. Nylon 66 has the highest melt temperature, i.e. 265 oC which would require a TPE with good, high temperature melt stability.
