Abstract

Certain preferred embodiments of the present invention relate to compositions for the production of sintered molded parts, components/parts produced therefrom, and methods for preparing such compositions. In accordance with certain embodiments, compositions for production of sintered molded parts comprise a metal-based, a ceramic-based, and/or a polymer-based powder, and a compaction aid, having 25 to 60 weight percent of a polyglycol, based on the total weight of the compaction aid, and 40 to 75 weight percent of a montan wax, based on the total weight of the compaction aid. The compaction aid may be present in an amount from about 0.1 to 5 weight percent, preferably 0.5 to 1.5 weight percent, based on the total weight of the composition. The composition may also include a lubricant such as, for example, MoS2, WS2, BN, MnS, and/or carbon.
