Cesa™ Fiber Additives Light Stabilizers for Synthetic Fibers and Nonwovens Non UV-stabilized fibers exposed to sunlight can suffer color fading and molecular changes that degrade their chemical and mechanical properties, leading to fraying and breakages. Unlike topical finishing treatments, which involve the addition of chemicals in a post-treatment water bath, the additive concentrates are incorporated into the polymer during spinning. KEY BENEFITS Avient’s UV stabilizers for fibers provide the following benefits: • High active ingredient loading options available • Little or no effect on processing speeds so plant productivity can be maintained at the highest levels • Resistance to interaction with fertilizers, pesticides and bleaching agents in the manufacturing and end-use environment • Can be combined with colors and with other additives (e.g., flame retardants) into a single combination concentrate for convenience • Product guidance and technical assistance from our experts PRODUCT BULLETIN Copyright © 2022, Avient Corporation.

With the help of select colorants, fiber reinforcements and additives, we customize these polymers to meet the demanding requirements of our customers’ applications. Typical applications are surgical instruments and thin walled tubing • Brilliantly colored: Proven expertise in coloring high temperature polymers, in both transparent and translucent shades, including bright whites, special effects and other hard-to-achieve colors. • Laser markable (IR and UV) • Fiber-reinforced for even greater mechanical properties What do you want to manufacture?
