This disclosure relates to a lubricant powder composition that is made from a combination of wax, grease thickener, and additives. The lubricant powder composition exhibits low frictional, and improved mechanical stability in high temperature environments. This disclosure further relates to the use of a lubricant powder composition in a mechanical component.

Wax-containing, organic thickened lubricant powder

The invention relates to grease compositions containing high viscosity index polyalphaolefins (HVI-PAO) and polyurea thickeners. The use of HVI-PAOs and polyurea thickeners in a bi-modal base stock grease application provides favorable frictional properties and improved overall performance.

High viscosity index PAO with polyurea thickeners in grease compositions

Polyurea compounds are prepared by reacting amines and polyisoyanates in the presence of a liquid diluent in a high-pressure impingement mixing device under conditions sufficient to produce polyurea compounds having the consistency of a powder and in which diluent is dispersed.

Process for preparing fine powder polyurea and greases therefrom

A system and device for preparing polyurea compounds. The system comprising a chamber for reacting amines and isocyanates in the presence of a liquid diluent in a high-pressure impingement mixing device under conditions sufficient to produce a polyurea compound having the consistency of a powder and in which diluent is dispersed.

Manufacturing device and system for preparing fine powder polyurea and greases therefrom

A grease composition having low noise characteristics is prepared by shearing a mixture of a base oil and a thickener for a time sufficient to reduce substantially all of the thickener to particles below 500 microns in size; and then processing the sheared mixture to a grease.
