Abstract:

A conductive polyoxymethylene composition comprising a first polyoxymethylene component, a conductive filler, at least one boron oxyacid or salt thereof, and at least one first polyamide oligomer is disclosed. The first polyoxymethylene component comprises a copolymer of oxymethylene, a homopolymer of oxymethylene, and mixtures thereof, and is present in an amount of from about 50 to about 99.5 weight percent based on the total weight of the composition. The conductive filler is present in an amount of from about 0.1 to about 40 percent by weight based on the total weight of the composition. The boron oxyacid or salt thereof and the first polyamide oligomer stabilize the composition such that articles formed therefrom exhibit reduced or eliminated deterioration. Further, when exposed to higher temperature, pressure, and high-fuel content environments, the articles maintain the desired physical properties.
