摘要： A polyester composition comprising, based on the total weight of the polyester composition, a first polyester and a second polyester, wherein a weight ratio of the first polyester to the second polyester is 80:20 to 20:80, preferably 60:40 to 40:60; 5 to 60 weight percent (wt %), preferably 5 to 50 wt % of a reinforcing filler; and 5 to 60 wt %, preferably 10 to 50 wt %, more preferably 20 to 50 wt % of an inorganic filler having a specific gravity of greater than 3 grams per cubic centimeter, as determined in accordance with ASTM D792, wherein a molded article comprising the polyester composition has a sound transmission loss of greater than 30 dB, preferably 35 to 50 dB, more preferably 36 to 45 dB, as determined at 1,250 Hz according to ASTM E1050 using a molded disc with a diameter of 100 mm and a thickness of 3.2 mm.
