Abstract:
A grease composition is produced by mixing a thickener comprising a fluoro resin and a second thickener component (a metallic soap, a complex metallic soap, an N-substituted terephthalamic acid metal salt, organic bentonite or a calcium sulfonate complex) into a base oil. This grease composition is excellent in heat resistance, load carrying capacity, water resistance, rust protection, lubricating life and the like. A rolling apparatus filled with the above grease composition has excellent lubricating ability and is long-lived under high-temperature conditions. Moreover, a grease composition is produced by mixing a thickener comprising a fluoro resin and carbon black as a second thickener component into a base oil. This grease composition is excellent in heat resistance, water resistance, rust protection, lubricating life, electric conductivity and the like. A rolling apparatus filled with the above grease composition has excellent electric conductivity and is long-lived under high-temperature conditions.

Abstract:
A lubricant for a run-flat tire system includes a water soluble, or water-miscible carrier, a thickener, and a surfactant. The thickener hereof retains its rheological properties and is not subject to permanent thinning shear. The base fluid is, preferably, a water-soluble polyhydroxyl or other polyhydric compound and the thickener is preferably a clay. When admixed with a surfactant and, optionally, a lubricity agent, the lubricant exhibits long term stability and (is resistant to heat buildup.) prevents the buildup of heat in the tire assembly when the tire is in the run flat condition.
Abstract:
A subject of the invention is a lubricating grease, characterized in that it contains: from 70 to 95% by weight of a mixture comprising at least a first ester of fatty acid and of sorbitan and at least a second ester of fatty acid and of polyoxyalkylated sorbitan, these esters being present in quantities by weight, relative to the weight of the said mixture, of 10 to 90% and 90 to 10%, respectively; and from 5 to 30% by weight of at least one thickening agent. A subject of the invention is also a preparation process for a grease according to the invention, as well as use as a lubricant of such a grease. A subject of the invention is also a vehicle wheel containing a grease according to the invention.
Abstract:
A grease for rock bit lubrication and other high temperature bearing applications is provided comprising a high viscosity index polyalphaolefin synthetic base fluid in combination with an alkylated naphthalene base fluid.
Abstract:
A composition that can be used as lubricant for high electric field including spark plug boots is disclosed. The composition comprises, or is produced by combining, a halogenated oil such as a perfluoropolyether, a polytrichlorofluoroethylene, a fluorosilicone, or combinations of two or more thereof; a basic thickener; and optionally an additional thickener in which the basic thickener is a metal hydroxide, a metal salt, an ammonium salt, or combinations of two or more thereof. The optional additional thickener is polytetrafluoroethylene, talc, silica, clay, boron nitride, metal soaps, titanium dioxide, polydimethylsiloxane, polyurea, polyurethane, or combinations of two or more thereof. Also provided is a spark plug boot that comprises the composition applied thereto.
Abstract:
A lubricating grease composition including the combination of an oil base, a thickener, and bismuth preferably in the form of a bismuth carboxylate. The grease has excellent film strength, improved “anti-washout” capabilities, and, depending on the thickener used, may have no dropping point, meaning that the oil will not separate out at elevated temperatures.
Abstract:
An open gear lubricant has a lubricant base comprising a major amount of a vegetable oil and a minor amount of a solid inorganic lubricant, thickened with a bidegradable organoclay gellant.
Abstract:
A heavy-duty lubricating grease is shown which includes a synthetic fluid base and a thickener system. The heavy-duty grease can be used in both rolling element and journal type rock bit bearings to drill in heavy-duty, high temperature applications, such as in the bearing structures of rock bits used to drill hot subterranean formations.
