Abstract: A polyamide composition comprising: (a) 30 to about 60 weight percent of at least one semi-aromatic polyamide comprising: (i) 63 to about 70 mole percent hexamethylene terephthalamide repeat units; and (ii) about 30 to about 37 mole percent hexamethylene decanamide or hexamethylene dodecanamide repeat units; (b) 3 to 30 weight percent of at least one flame retardant; (c) 0.02 to 0.65 weight percent of a lubricant; (d) 5 to 50 weight percent of at least one inorganic reinforcing agent; (e) 0 to 5 weight percent of a nucleant; and (f) 0.2 to 10 weight percent of at least one flame retardant synergist. Such compositions exhibit a combination of a molding cooling time of less than or equal to 9 seconds; a reflow peak temperature of at least 270° C.; and a flammability of V-0 measured according to UL-94 flammability test.
