RELATIVE TOXICITY OF SELECTED POLYMERIC MATERIALS DUE TO THERMAL DEGRADATION.
Abstract
A thermal-decomposition-toxicity index is defined that includes the rate and temperature of thermal decomposition, as well as the quantity and toxicity of the resulting decomposition products. By means of this index, the relative toxicity due to thermal degradation is determined for selected heat-resistant thermoplastics and other polymeric materials. These are listed below in the order of least toxic first, most degrees F: Teflon TFE; Teflon FEP; Kapton polyimide film; Viton (assumed equivalent to Fluroel for this study): Perfluoropropylene polymer: and Carboxy nitroso rubber. At lower temperatures, e.g., at 300 to 400 degrees F, the order of merit appears somewhat altered for Kapton polyimide film, Viton, and perfluoropropylene polymer. (Author) (Author-PL)
