See full text

Non-fibrous-reinforced thermoplastic molding compositions comprising a metal powder as a heat stabilizer are provided. The metal powder has a weight average particle size (dm) of at most 1 mm and the metal in the metal powder is selected from the group consisting of elementary metals from Group VB, VIB, VIIB and VIIIB of the Periodic Table, and mixtures thereof. A thermoplastic polyamide is also provided with an Mw of at most 50,000 g/mol, or a blend of at least two thermoplastic polymers with Tmelt or Tg differing by at least 20° C., or a second thermostabilizer. The invention also relates to the use of these compositions in high temperature applications.
