AN ALTERNATIVE FLAME RETARDANT SOLUTION FOR CATEGORY CABLES CASE STUDY: MAXXAM™ FR POLYPROPYLENE Challe nge Accepted. MEETING FR GOALS IN DATA CABLES WITH AN ALTERNATIVE TO FEP Maxxam FR materials can provide cost savings and improved processing capabilities when used in category 5e cables and above. FEP provides such characteristics, and thus is commonly chosen to provide category cable insulation.

Depending on the cable construction, fluorinated ethylene propylene (FEP) is the preferred polymer used for insulation of a conductor or as jacketing of one or more cables. For identification purposes or safety reasons, these cables often need to be marked. Examples include: • Data transmission cables • Optical fiber cables PRODUCT BULLETIN 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.

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. Temperature fluctuations in the environment where the cable is installed can mean the armoring and the other cable materials expand and contract at different ratios, further increasing the risk of cracking in the cable jacket. 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.
