    摘要: This invention relates to a flame retardant polyamide composition comprising a semi-aromatic polyamide, a flame retardant system and a reinforcing agent, wherein the semi-aromatic polyamide comprises units derived from dicarboxylic acids comprising terephthalic acid and aliphatic dicarboxylic acids, and aliphatic diamines. In the semi-aromatic polyamide the aliphatic diamines consist of 10-70 mole % of a short chain aliphatic diamine with 2-5 C atoms and 30-90 mole % of a long chain aliphatic diamine with at least 6 C atoms; the dicarboxylic acids consist of 5-65 mole % aliphatic dicarboxylic acid and optionally aromatic dicarboxylic acid other than terephthalic acid and 35-95 mole % terephthalic acid; and the combined molar amount of terephthalic acid and the long chain aliphatic diamine is at least 60 mole %, relative to the total molar amount of the dicarboxylic acids and diamines. The invention also relates to a housing for an electrical/electronic (E/E) connector and use therein of the flame retardant polyamide composition, to a surface mounting process wherein the E/E connector is used and to a surface mounted device comprising the E/E connector.
