摘要

Electrically conductive polyoxymethylene moulding materials (I) are cliamed, contg. (A) 70-90 wt.% polyoxymethylene homo-or copolymer, (B) 5-26 wt.% impact modifier, (C) 4-8 wt.% conductive carbon black with BET surface area 400-1000 m2/g and (D) 0-2 wt.% polyamide and/or Bisphenol A/epichlorhydrin polycondensate. Pref. (B) is a thermoplastic polyurethane (TPU) and/or a graft copolymer rubber.
