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.
