Reduction of Hydrogen Cyanide Concentrations and Acute Inhalation Toxicity fromFlexible Polyurethane Foam Combustion Products by the Addition of Copper Compounds. Part 3. The Effect of Copper Additives on the Flammability Characteristics of Flexible Polyu

摘要

The report addresses the issue of whether the addition of a copper compound to aflexible polyurethane foam would affect the flammability characteristics of the foam. The following properties were examined: (1) ignitability in three systems (the NBS Toxicity Test Method, the Cone Calorimeter, and Lateral Ignition and Flame Spread Test (LIFT)), (2) heat release rate under small-scale (Cone Calorimeter) and medium-scale (furniture calorimeter), (3) smoke obscuration (Cone Calorimeter), and (4) rate of flame spread (LIFT). In all cases, no differences in flammability characteristics between the treated and untreated foam were observed.
