Popis: The purpose of this study was to investigate the composition and toxicity of fluoroplastic F-40 thermodestruction products at 300-500 degrees C and to identify the maximally allowable temperature for their safe use. When heated over 400 degrees C, the products of luoroplastic F-40 evolution included such compounds as hydrogen fluoride, fluro-organic compounds, carbon monoxide, formaldehyde. When heated at 500 degrees C, the thermodestruction products caused the highest mortality rate of mice. The pathogenesis and clinical development of fluoroplastic F-40 poisoning are primarily associated with fluoro-compounds. It is concluded that the temperature 300 degrees C is the maximum temperature at which tetrafluroethylene-based polymers can be used.
