A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer in combination with a tribological modifier system. The tribological modifier system may include the combination of a fluoropolymer with a high density polyethylene, such as an oxidized high density polyethylene. The particular formulation provides a synergistic blend of properties. For instance, the polymer composition not only has an excellent surface appearance when molded into articles but has excellent low friction characteristics when tested against aluminum.
