ECCOH™ Specialty Solutions Helping Cable Manufacturers Meet CPR Standards PRODUCT BULLETIN ECCOH™ Low Smoke and Fume Non-Halogen (LSFOH) formulations offer a range of non- halogen, flame retardant solutions that enable manufacturers to meet the Construction Products Regulation (CPR) standards set out by the harmonized European Standard, EN13501. KEY CHARACTERISTICS • Highly flame retardant: Flame retardancy helps prevent fire and to limit damage if one starts • Non-halogenated: During a fire, there are no ingredients to cause acidic gas emissions from the polymer, which can damage equipment and buildings • Low smoke: In the event of fire, people are more able to find the escape exit and fire fighters can quickly find the source of the fire • Low toxicity: People are not likely to be overcome by toxic fumes • Low dripping: No flaming droplets are likely to propagate a fire or injure evacuees • Manufacturing efficiency: Easy processing with a smooth surface finish MARKETS AND APPLICATIONS The ECCOH range of specialty polymers help manufacturers meet CPR requirements for power, control and communication cables (including optical fiber cables) used in buildings. Optical fiber sheathing1 5702 SEPAP 8.0 10.5 140 47 Cca Specially formulated for optical fiber applications where the SEPAP UV test is required.

Our extensive portfolio of specialty colorants helps producers of synthetic fibers and nonwovens achieve brilliant colors and optimal dyeing of polyester, polypropylene and polyamide fibers. Avient offers a wide range of functional additive concentrates specially formulated for filament, staple and nonwoven fiber processes. It works by injecting liquid color at high pressure into the polymer melt- flow between the end of the extruder, or melt-pipe, and the spin head.
