摘要:
A polyoxymethylene composition, polyoxymethylene parts, and a process for the production of polyoxymethylene. The polyoxymethylene composition contains one or more polyoxymethylene species, an aqueous anionic polyurethane dispersion, phenolic antioxidant(s), and optionally, colorant, filler, and conventional additives. The composition exhibits improved resistance to non-ferrous metal corrosion.
