Styrene acrylate copolymer 80-95%) CAS# Confidential. OSHA PEL: Not listed. ACGIH TLV Not listed. LD50: Not Available. LC50: Not Available. Wax (5-15%) CAS# Confidential. OSHA PEL: Not listed. ACGIH TLV Not listed. LD50: Not Available. LC50: Not Available. Silica (1-3%) CAS# Confidential. OSHA PEL: Not listed. ACGIH TLV: 10 mg/m3. LD50: Not Available. LC50: Not Available. Physical Data Physical State: Solid. Melting/Freezing Point: Not available. Boiling Point: Not available. pH: Not available. Vapor Pressure: Not available. Vapor Density (Air=1): Not available. Evaporation Rate (Butyl Acetate=1): Specific Gravity (H2O=1): About 1.2 at 20°C (68°F). Solubility in Water: Negligible. Solubility in Solvents: Partially soluble in toluene and tetrahydrofuran. Coefficient of water/oil Distribution: Not available. Appearance and Odor: Black powder, slight plastic odor. Odor Threshold: Not available. Fire and Explosion Hazard Data ___________ Minimal fire hazard. Large quantities may cause risk of dust explosion. Flash Point (Method Used): Not applicable. Flammable Limits Lower Explosive Limit: Not applicable. Upper Explosive Limit: Not applicable. Auto-Ignition Temperature: Not applicable. Explosion Data Sensitivity to Mechanical Impact: Not available. Sensitivity to Static Discharge: Not available. Extinguishing Media: Water, foam or dry chemical. Special Fire Fighting Procedures: Fight fire from upwind position. Avoid inhalation of smoke or gases. Wear self-contained breathing apparatus. Cool the container with water spray. Hazardous Combustion Products: Carbon monoxide. Also produces carbon dioxide. Toxicological Properties Routes of Entry: Inhalation, Ingestion, Eyes, Skin. Effects of Acute Exposure: Not available. Effects of Chronic Exposure: Not available. In a study in rats of chronic inhalation exposure to a typical toner, a mild to moderate degree of lung fibrosis was observed in 92% of the rats in the high concentration (16 mg/m3) exposure group. A minimal to mild degree of lung fibrosis was observed in 22% of the rats in the middle (4 mg/m3) exposure group. No pulmonary change was reported in the lowest (1 mg/m3) exposure group, the most relevant level to potential human exposures. Exposure Limits (ACGIH TLV): Inhalable Particulates: 10 mg/m3 Respirable Particulates: 3 mg/m3 Irritancy: Not available. Sensitivity: Not available. Carcinogenicity IARC Carbon Black: Group 2B "Possible Carcinogen." This classification is given to chemicals for which there is inadequate human evidence, but sufficient animal evidence on which to base an opinion of carcinogenicity. The classification is based upon the development of lung tumors in rats receiving chronic inhalation exposure to free carbon black at levels that induce particle overload of the lung. Studies performed in animal models other than rats did not show any association between carbon black and lung tumors. Moreover, a two-year cancer bioassay using a typical toner preparation containing carbon black demonstrated no association between toner exposure and tumor development in rats. NTP: No components are listed. OSHA: Carbon black is designated hazardous according to OSHA 29 CFR 1910.1200. Reproductive Toxicity: Not available. Teratogenicity: Not available. Mutagenicity: Not available. Names of Toxicologically Synergistic Products: Not available. Reactivity Data Stability: Stable in general. Materials to Avoid: None. Polymerization: Will not occur. Hazardous Decomposition or Byproducts: Combustion products include carbon monoxide and carbon dioxide. Incompatibility: Avoid exposure to strong oxidizers. Preventive Measures Personal Protective Equipment Respiratory Protection: Not normally required. For large spills, use dust respirator mask during cleanup. Protective Gloves and/or Eye Protection: Not normally required. For large spills, use leather gloves and safety goggles during cleanup. Engineering Controls Ventilation: Outside of normal ventilation, not normally required. Other Protective Equipment and/or Hygienic Practices: None. 8 - English
