Over the course of two decades, the Company has transformed from a company focused on commodity products, to a specialty formulator of sustainable solutions. We believe our innovation pipeline remains robust, as we leverage our formulation expertise and sustainable solutions portfolio. Further, as a result of Avient's portfolio shift to a pure play specialty formulator, it has completed several acquisitions and divestitures which have resulted in a significant amount of intangible asset amortization.

These continuous fiber-reinforced polymer composites are ideal in applications where high stiffness and light weight performance are critical. Benefits include: • Alternating longitudinal (axial) fibers for flexural & tensile strength and circumferential (biaxial) fibers for crush & burst resistance • Manufactured continuously, at a much higher rate than standard filament winding • Resin matrix and fiber loading formulated to meet your property requirements • Tubing in standard or customized diameters and lengths STANDARD SIZES To learn more about Avient advanced composite solutions, call +1.844.4AVIENT or visit www.avient.com/composites Copyright © 2020, Avient Corporation.
