Cesa™ Fiber Additives Antimicrobial Additives for Synthetic Fibers and Nonwovens Bacteria and other microorganisms can cause unpleasant odor, discoloration and even degradation of surface qualities in textiles and nonwovens. The Cesa™ Fiber Additives portfolio includes antimicrobial concentrates that help prevent these problems by limiting the growth of microorganisms. PRODUCT BULLETIN KEY BENEFITS Avient’s antimicrobial concentrates for fiber applications provide the following benefits: • High active-ingredient loading which translates to excellent efficacy at low let-down ratios • Easily withstand 50 washings in ISO 20743 standard tests • Also applicable for bi-component technology • Low levels of abrasiveness means higher process performance—reducing cost in the spinning phase • 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 Copyright © 2022, Avient Corporation.

This often involves food contact approvals that extend beyond the EU or the USA, and take into consideration specific regions or other food safety standards. Cesa™ No-fog Additives & OnCap™ Anti-fogging Additives Minimizing the negative effect of condensation on the film surface is one of the key needs during the food packing process and on the shelf. Cesa™ Nox Additives Cesa Nox antioxidant solutions help plastics maintain shine and transparency while preventing yellowing, surface cracking, and odors often caused by oxidation and heat aging.

PRODUCT BULLETIN Cesa™ Nox A4R Additives for Recycling Polyolefin Antioxidant for Enhanced Recycling RECYCLED MATERIAL IN A CHANGING MARKET Legislation globally is driving change towards increased quantities of post-consumer recycled materials (PCR), further encouraged by the implementation of usage targets and new tariffs. DESIGN FOR RECYCLING Cesa™ Nox A4R is designed for recycling. Cesa Nox A4R is formulated to help: • Brand owners who need to maximize their PCR usage up to 100% to achieve sustainability and recyclability targets • Recyclers involved with flake or pellets dealing with multiple processing defects • Convertors of bottles, film, and sheet who need to maintain high-quality levels of PCR Performance enhancement antioxidants such as Cesa Nox A4R are valuable for many stakeholders within the circular economy, and indeed anyone seeking to achieve high-quality levels in their recyclate while operating with ever-increasing quantities of PCR.

PRODUCT BULLETIN Non-PFAS Polymer Process Aids for Extrusion in Polyolefins Cesa™ and Hiformer™ Non-PFAS Process Aids are formulated without the use of fluorochemicals.
