One method is through the use of stabilizers that react with radicals created from UV exposure, inhibiting polymer degradation. Many CESA Light products include CESA Nox additives, which also aids in polymer protection. 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.

During processing, polymers often degrade due to oxygen and heat exposure which causes such things as discoloration, gels, and black spots. Brand owners, recyclers, and convertors require high-performance and cost-effective solutions that can make recycling easier, allowing them to continue using greater quantities of PCR. Sustainability Spotlight Recycle Solutions KEY CHARACTERISTICS • Designed for polyolefin recycling and to enhance circularity • Protects polyolefins against degradation caused by oxygen and heat during processing • Provides improved stability against oxygen degradation and discoloration • Stabilizes the polymer to reduce creation of new gels and black spots • Excellent performance at low dosage levels MARKETS & APPLICATIONS • Recycled polyolefins • Packaging, consumer & others • High-value polyolefin applications with recycled material content • Virgin polymers which will be recycled after the use phase Copyright © 2022, Avient Corporation.

Gravi-Tech™ BIO Bio-Based Formulations Gravi-Tech™ BIO bio-based formulations are density modified engineered polymers that contain partially bio-based resin from renewable plant sources. They offer a more sustainable alternative to density modified grades based on prime/virgin polymers. These polymer formulations have been developed to achieve equivalent performance to prime density modified solutions with added sustainability benefits.

CESA™ Slip Additives Lubrication PRODUCT SELECTION GUIDE Many polymer processing operations need lubrication to improve the process flow and/or part. They act as plasticizers to improve the flow of the polymer through the process (extrusion, injection molding, extrusion blow molding, etc), reducing the heat and energy needed.
