<P>PROBLEM TO BE SOLVED: To provide a molding composition having a better heat aging property than well-known compositions, and a molding article therefore usable at a high continuous use temperature. <P>SOLUTION: The molding composition is a fiber-non-reinforced thermoplastic molding composition containing a metal powder as a thermal stabilizer, wherein the metal powder has a weight-average particle diameter (dm) of 1 mm at the maximum; and a metal in the metal powder is selected from the group consisting of metal elements of group VB, group VIB, group VIIB and group VIIIB in periodic table and mixtures thereof. The composition, in addition to the metal powder, contains a thermoplastic polyamide having Mw of 50,000 g/mol at the maximum, or a blend of at least two thermoplastic polymers having Tmel or Tg different by at least 20°C or a second thermal stabilizer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
