r* TH| DlSCOVtftV COMPANY POLYSTYRENE Union Carbide's polystyrene homopolymers, SAN copolymers, and rubber modified impact polystyrenes have a low order of toxicity. Their use in usual manufacturing processes will not ordinarily result in conditions defined as hazardous to health in Che Occupational Safety and Health Act of 1970. Polystyrene resins are classified as being slow burning, and when burned, the primary combustion products are carbon dioxide, carbon monoxide, and water. Rubber modification does not significantly change the combustion products. It has been determined chat the combustion products of polystyrene are no more hazardous than chose from wood, paper, or other natural products. The self-ignition temperature of polystyrene resins ranges from 800 to 90Q*F. Based on laboratory studies in air at 500*F., a typical impact polystyrene is expected to generate 0.04 pound of fumes per ton of resin processed on typical sheet extrusion equipment. The emissions were primarily styrene monomer, but included a small amount of antioxidant, and they resulted almost entirely from volatilization rather chan oxidative degradation. * * ''A, A, D'Onofrio Product Manager ucc 049759 * only tor tr> fact that tud*A raoortad hart and all ooin.om ra that# of oiial'f'td aprt.
