PRODUCT BULLETIN Syncure™ XLPE Cross-linkable Polyethylene Formulations DBDPE-free solutions for low voltage cable systems The Syncure™ XLPE 200 Series is comprised of engineered, moisture cross-linkable solutions formulated without decabromodiphenyl ethane (DBDPE). With excellent temperature ratings and flame performance, these flame retardant polymers are used for insulation in low voltage cable systems, such as building wires, tray cables, and service entrance cables.

BENEFITS • High additive loading for optimal UV stabilization • Solutions available for a large number of injection molded polymers including PP, PE, PS, HIPS, ABS, SAN, PA (nylon), PBT, Co-PET, PC, POM and TPU • Can be combined with colors and other additives in Smartbatch™ solutions • Formulations can be customized to meet specific regulatory compliance, e.g., EU and US food contact, toy, UL 94 recognition PRODUCT BULLETIN Copyright © 2023, Avient Corporation.

Cesa WithStand Antimicrobial Additives can be used across a wide range of polymer types. They provide a proven, effective and durable solution for countering microbe growth in finished plastic parts used in health and wellness applications. Cesa WithStand solutions include technical assistance to customize the additive dosage, as well as support with processes and specifications, helping to reduce time to market and saving time and cost in the development process.

THE SOLUTION This coordinated effort resulted in the innovative Modular Protective System (MPS) portable structure, which incorporates an Edwards-designed collapsible truss framework and Avient’s GlasArmor™ ballistic resistant composite panels. GlasArmor panels made with fiber-reinforced polymer (FRP) composites provide excellent ballistic stopping power for the MPS while meeting the requirement of being lightweight and portable. With our hardware fabrication capabilities and Avient’s knowledge of composite ballistic protection technology, we were able to create modular systems that reduce time and logistic requirements for our brave soldiers.” 1 https://www.erdc.usace.army.mil/Missions/Military-Engineering/Deployable-Force-Protection-Demo/ To learn more about ballistic resistant solutions from Avient, visit avient.com or click to request a quote.

Low Dissipation Factor (Df) Material – Our solutions use a base formulation that has a Df value of less than 0.002. Good Dimensional Stability – Our solutions are formulated to meet dimensional tolerances within +/- 0.2mm. Better Performance-to-Cost Ratios – Traditionally used materials can cost 30–40% more than a thermoplastic solution at only slightly better performance.

ColorMatrix™ Amosorb™ SolO2: a recyclable solution Recyclability has become a fundamental requirement for convertors and brand owners. Pressure from the media, the scientific community, end-consumers, and legislation is pushing members of the polymer industry value chain to play their part, in proposing alternative sustainable solutions that can perform in terms of recyclability. Providing solutions that are considered recyclable within the colored bottle stream will thus be an integral part of the recyclability strategy for both convertors and brand owners.
