Abstract
The overview of the literature for a 25-year period on the combustion and f ire-retardant performance of major commercial aliphatic nylons is presented . It is shown that aliphatic nylons are relatively easily ignitable materia ls which support combustion and are therefore required to be fire retarded for some applications. Nylons do not produce vision-obscuring smoke during combustion, and the toxicity of their combustion products is similar to or lower than that of many other man-made materials. Patent Literature and tec hnical publications on the fire retardancy of aliphatic nylons with halogen ated products, phosphorus-containing compounds, nitrogen-rich compounds, su lfur-containing, boron-containing and silicon-containing products are discu ssed. Miscellaneous inorganic additives and char-forming organic products a re also discussed. It is concluded that, in spite of significant attempts, no commercial solution of fire retardancy of aliphatic nylons without loss of mechanical properties is available.
