Flame - and Smoke-Retardant Polymer Systems.
Abstract
Experimental neoprene rubber compositions were prepared to investigate the feasibility of reducing smoke formation and improving other fire performance characteristics with incorporated additives. Specimens were tested in an NBS smoke density chamber under flame and nonflame exposure conditions. The smoke optical density and the concentrations of CO, CO2, NOx, hydrocarbons, hydrogen chloride and hydrogen cyanide were monitored during these tests. Ferric acetylacetonate by itself and in combination with poly(ammonium phosphate) reduced smoke optical density generated from neoprene foam under flame exposure conditions by approximately 10%. Cupric acetylacetonate, another candidate char formation catalyst evaluated in this work, catalyzed thermal degradation of the neoprene foam. Ferric acetylacetonate catalyzed the formation of CO under nonflame exposure conditions. This catalytic effect was destroyed by incorporating poly(ammonium phosphate) with ferric acetylactonate. Crosslinking catalysts more effective than those used in the presently reported work are needed to reduce smoke formation from neoprene foam significantly.
