These include high-temperature, engineering and recycled polymers. Customers are guided through a color development process at the earliest stages of their product development to establish high-impact colors for their brands, helping accelerate time to market. Impact modifiers, scratch resistance, and antioxidant additives are just a few examples.

ECCOH™ Low Smoke and Fume Non-Halogen Formulation 5983 With high environmental stress cracking resistance for power cable jacketing The new ECCOH™ 5983 formulation helps prevent environmental stress cracking in low and medium-voltage armored power cables, helping to prevent costly cable damage and disrupted power supply. The ECCOH 5983 formulation has been developed to help prevent stress cracking in armored cables by offering high tear strength and elongation at break at temperatures ranging from -25°C to 90°C. MARKETS AND APPLICATIONS • Cable jackets for low and medium-voltage power cables with metal armoring, typically installed underground or where installation requires them to be bent • Armored cable applications that require compliance with LTS1 requirements as per the BS 7655-6.1 standard IMPACT • High environmental stress cracking resistance • High tear strength and elongation at break at temperatures ranging from -25°C to 90°C • Flame retardant performance • Limiting oxygen index (LOI) of 36% • Exceeds BS 7655-6.1:1997 standard criteria for LTS1–LTS4 for complex designs and armored cables PRODUCT BULLETIN Cable jacket liable to cracking Power Cable Cross Section Metal armoring 1.844.4AVIENT www.avient.com Copyright © 2023, Avient Corporation.

THE SOLUTION Gravi-Tech™ density-modified formulations are unique, high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. THE IMPACT Gravi-Tech high-density formulations enabled API to design and mold a patented, full-opening flapper valve that is not only unique in the market, but also offers important cost, performance and environmental advantages over brass Elimination of lead = increased safety and compliance: Replacing brass with Gravi-Tech high-density formulations eliminates health and safety concerns about lead

It is widely used to manufacture films, bags, trays, bottles, and containers, and it has excellent overall properties such as impact and tensile strength, clarity, processability, colorability, and durability. For these reasons plastics for packaging play an important role in everyday life, however, due to the high volume and rather short usage life of plastic packaging items, they require appropriate management, especially at the end of their life. ISSUES WITH POST-CONSUMER RECYCLATES (PCR) Very often post-consumer recyclates (PCRs) are not of a good enough quality to withstand efficient processing, nor can they offer long-term stability for high-value or high-performance end applications.

There is more to measuring the sustainability of a company than just the physical impacts on the environment from manufacturing its products. Typically, environmental metrics are focused on the operational risk of raw material suppliers and polymer manufacturers – and the impact those products have on the planet. Avient focuses on ESG metrics that ensure employee safety, support a growing sustainable solutions portfolio, and positively impact our environment by reducing waste and energy consumption.
