Abstract

The paper presents the results of a study of the effect of fire retardants on the flammability and melt flow rate of aliphatic polyamides of the PA 66L, PA 610L, PA 66KS grades. The degree of this influence depends on the grade of polyamide, the type of fire retardant and its quantitative content. Among the selected grades of polyamides, polyamide PA 66L has the highest fluidity. The efficiency of using decabromodiphenyloxide and antimony trioxide to reduce the duration of residual combustion of polyamides of the studied brands is shown, compositions related to the category of «self-extinguishing» are determined.
