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.

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.

Cesa™ Flame Retardant Additives PTFE-free and Non-halogen for Polycarbonate Polycarbonate is a material of choice for E&E products as it provides very good impact strength, dimensional stability, and heat resistance.Some applications require the use of flame-retardant solutions to increase safety and ensure compliance with fire hazard standards. Avient’s PTFE-free and non-halogen Cesa™ Flame Retardant Additives for polycarbonate are formulated without PTFE and are non-halogen in accordance with the IEC 61249-2-21 standard. Provided in the form of additive concentrates, they can be combined with colors and other additives for a solution tailored to customers’ needs.

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. The performance of both Cesa solid and Hiformer liquid additives is effective at low concentrations in eliminating melt fracture (shark skin) and die buildup (die drool). KEY CHARACTERISTICS • Reduces melt fracture leading to fast time to clear • Reduces die buildup • Improves process efficiency • Retains ability to seal and print • Available in both solid and liquid • Offers low concentration efficiency • Reduces power requirements • Does not interact with other additives APPLICATIONS • Blown film • Profile extrusion • Tubing and pipe extrusion • Wire and cable applications • Extruded sheet • Applications in both virgin resin and PCR Copyright © 2024, Avient Corporation.

These include enhanced light resistance, high temperature resistance, ageing test resistance, low shrinkage, and many other performance criteria that can be required in the final application. UV Light Stabilizers Cesa™ Light Additives Long-term protection against weather degradation. Repellant Additives Cesa™ Aversive Technology Long-term protection against rats and termites.
