Flame- and Smoke-Retardant Polymer Systems
Experimental smoke-retardant PVC compositions and a reference base polymer were coated with alkyd- and epoxy-based intumescent paints. 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 oxygen were monitored during these tests. Although the coatings reduced smoke formation from the base polymer, they had an adverse effect on the performance of the smoke-retardant compositions. The commercial coatings used in this work were found to generate significant quantities of smoke. Other, recently developed coatings will be used in projected work. The intumescent coatings reduced the rates of carbon monoxide and hydrogen chloride formation, especially under nonflame exposure to a radiant energy source. The coatings contributed small amounts of nitrogen oxides to the combustion products. (Author)
