MATERIAL LIFECYCLE GLOSSARY OF TERMS Material Manufacturer - Raw material suppliers or processors who produce materials ready for manufacturing Reworkable Material - O� spec or scrap materials that are re-ground or re-worked back into the same supply or manufacturing process that produced them – these are not considered recycled Prime - Materials supplied that meet the required specification, ready for processing/ manufacturing Processor - Manufacturing of products ready for market e.g. molders and extruders Retail/Consumer - End user Reclaimer - Local recycling center for consumer goods Post-Consumer Recycle (PCR) - Materials derived from polymers reclaimed at the end of their lifecycle that have been through waste treatment Scrap Parts & Materials - Waste from the manufacturing process that cannot be reused within the same process or sold to the market Waste Treater - Regional industrial waste reclamation center Post-Industrial Recycle (PIR) - Material derived from scrap reclaimed within the manufacturing process that has been through waste treatment PRIME POST- CONSUMER RECYCLE (PCR) WASTE TREATER POST- INDUSTRIAL RECYCLE (PIR) REWORKABLE MATERIAL RETAIL/ CONSUMER RECLAIMER MATERIAL MANUFACTURER SCRAP PARTS & MATERIALS PROCESSOR

SHANGHAI – April 23, 2024 – Avient Corporation, a premier provider of specialized and sustainable materials solutions and services, announces the launch of a new range of OnColor™ durable orange nylon colorants developed to improve the heat and long-term color stability of cautionary, orange-colored polymers for high-voltage electric vehicle (EV) connectors. The new polymer colorants are available in several validated RAL, Pantone, and JPMA orange shades for compounding, injection molding, and extrusion. Avient Corporation provides specialized and sustainable materials solutions that transform customer challenges into opportunities, bringing new products to life for a better world.

OnColor™ Bio Colorants: polymer colorants that offer a wide array of bio-derived color concentrates and perform well with bioplastics Avient Corporation provides specialized and sustainable materials solutions that transform customer challenges into opportunities, bringing new products to life for a better world. Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint

Delivering comparable processing performance to traditional processing aids, Avient’s Cesa Non-PFAS Process Aid reduces friction between the polymer and the metal, allowing the polymer to be more easily extruded. Avient Corporation provides specialized and sustainable materials solutions that transform customer challenges into opportunities, bringing new products to life for a better world. Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint  

Wide selection of polymer jacketing materials Vectran® Liquid Crystal Polymer Fiber Explore material solutions for fiber optic cable, including engineered fibers, specialty engineered materials, colorants, and additives

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. Processing conditions can cause material properties to shift from the values stated in the information.

One angle is to offer chemical foaming agents that help reduce plastic material use. These CFAs are the result of Avient’s combined experiences in the development of chemical foaming agents for automotive plastic components and polymer solutions for healthcare applications. The products help reduce material use by up to 20% depending on part geometry and wall thickness.
