摘要： The thermoplastic polymeric molding composition of the invention has good moldability in shaping by injection molding, extrusion molding and compression molding and capable of giving shaped articles having good machinability in mechanical working such as cutting, grinding and latching. The composition is compounded from 2 to 70 parts by weight of a thermoplastic polymer such as a polyamide resin and from 98 to 30 parts by weight of a metallic filler such as zinc powder and zinc oxide powder having a surface coated with a water repellent agent such as silane coupling agents, titanate coupling agents and silicone fluids in a specified amount. A part of the above mentioned particulate filler may optionally be replaced with a fibrous filler such as glass fibers and carbon fibers so that the shaped articles of the molding composition may be imparted with increased impact strength.
