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. Values reported as “typical” or stated without a range do not state minimum or maximum properties; consult your sales representative for property ranges and min/max specifications.

Because antimony trioxide is a fine powder, the most likely exposure scenario is due to dust that could form when the bags are being discharged in an industrial setting. Antimony trioxide that enters the soil will likely react with any iron, aluminum and manganese compounds that might be present in the soil to form other antimony compounds. EXPOSURE HUMAN HEALTH SAFETY ASSESSMENT Human Health Consumers are not likely to be exposed to because it is not sold directly to consumers nor are sales to consumer markets endorsed.
