Meets strict flame-retardant compliance

The non-GAAP financial measures include Free Cash Flow and Adjusted EBITDA Margin. A reconciliation of each historical non-GAAP financial measure with the most directly comparable GAAP financial measure is attached to this presentation, which is posted on our website at www.avient.com. This is due to the inherent difficulty of forecasting the timing and amount of certain items, such as, but not limited to, mark-to-market adjustments associated with benefit plans, environmental remediation costs, acquisition-related costs, and other non-routine costs.

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. 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.

Combining colorants with performance-boosting additives, these formulations help to protect non-woven polymer fabrics, fibers and filaments from UV light-induced degradation without any tradeoffs in performance. They feature excellent color fastness at low loading levels, and can include flame retardants to meet stringent safety standards.
