    Abstract: The invention is concerned with a flame retardant polyamide composition in which melam is the flame retardant component. Very advantageous are polyamide compositions having a melting temperature of at least 260° C. preferably 280° C. in which for the first time with a non-halogen containing flame retardant at relatively low concentration high flame retardancy ratings can be obtained. Preferably the melam contains less than 2.0% by weight residual catalyst. The compositions are useful for cablecoatings, tubing, films, fibers and electric or electronic components.
