Eco-conscious packaging compositions are preferred by customers, pushing convertors and brand owners to use sustainable materials—perhaps partially based on renewable or bio-derived sources—that also ensure food contact compliance.

Be Sustainable Eco-conscious consumers value recycled content, renewable resources and resource efficiency.

It is to enable our customers’ innovation and sustainability goals through world class products and services and excellence in the four cornerstones of: WE HELP OUR CUSTOMERS MAKE PRODUCTS THAT ARE MORE SUSTAINABLE IN 8 DIFFERENT WAYS: • Lightweighting • Reduced Energy Use • Volatile Organic Compound Reduction • Recycle Solutions • Bio-polymers • Eco-conscious • Sustainable Infrastructure • Human Health & Safety For more information on how we can help, visit avient.com 1.844.4AVIENT www.avient.com Copyright © 2021, Avient Corporation.

KEY CHARACTERISTICS • Chemical resistance • Maintaining high impact performance at low temperatures • Low moisture uptake • Dimensional stability comparable to nylon • Higher impact resistance than short fiber alternatives • Eco-conscious alternative to nylons • More cost-effective solution than specialty nylons • Available in non-PFAS* formulations to achieve UL 94 V-0 flame rating at 1.5 mm MARKETS & APPLICATIONS These materials are for use in applications traditionally made of metal requiring moisture, chemical and cold impact performance requirements, including: • Industrial – pipes, tubing, fluid management • Electrical & Electronics – connectors, battery components, battery housings • Transportation – under-the-hood fuel/ chemical contact components, non-structural interior components • Oil & Gas – fuel pump components, fuel doors PRODUCT BULLETIN * Non-PFAS flame-retardant (FR) grades are manufactured without intentionally added PFAS-based raw materials.
