▎ 摘  要

NOVELTY - A polyamide molding composition comprises 22-70 wt.% partially crystalline copolyamide (A) formed from 27.5-40 mol% 1,6-hexanediamine (a1), 10-17.5 mol% at least one cycloaliphatic diamine (a2) excluding 1,3-bis(aminomethyl)cyclohexane, 0-5 mol% at least one 2-35C diamine (a3) different from the monomers (a1) and (a2), 45-50 mol% 1,6-hexanedioic acid (a4) and 0-5 mol% at least one 2-44C dicarboxylic acid (a5) other than the monomer (a4), 30-70 wt.% at least one filler (B), and 0-8 wt.% at least one additive (C) differing from components (A) and (B). The content of monomers (a1)-(a3) is 50 mol% or less. The content of monomers (a4) and (a5) is 50 mol% or less. USE - Polyamide molding composition for molded product e.g. household appliances, unpainted visible component, vehicle interior or trunk, household components, mechanical engineering, electronic devices, furniture, fan blades, gear levers, rocker switches, buttons, rotary controls, handles, operating elements for seat adjustment, control levers, controls, drawers, holders for additional devices, cup holders, luggage hooks, covers, light switches, razor heads, scissors, threaded rods, insulin pumps, housings and decorative elements (all claimed). ADVANTAGE - The composition provides molded product having excellent surface quality and glossiness.
