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:
Die Erfindung betrifft einen lebensmittelverträglichen Hochtemperaturschmierstoff, insbesondere ein Hochtemperaturöl und ein Hochtemperaturfett umfassend folgende Komponenten: a) mindestens ein Öl ausgewählt aus einem Trimellitsäureester oder einem Gemisch aus verschiedenen Trimellitsäureestern, Alkylaromaten, vorzugsweise ein aliphathisch substituiertes Naphthalin oder Estoliden; b) einem hydrierten oder vollhydrierten Polyisobutylens oder einer Mischung aus hydrierten oder vollhydrierten Polyisobutylen und; c) Additive einzeln oder in Kombination.

Abstract:
The invention relates to a food-grade high-temperature lubricant, in particular a high-temperature oil or a high-temperature grease comprising the following components: a) at least one oil selected from a trimellitic acid ester or a mixture of various trimellitic acid esters, alkyl aromates, preferably an aliphatically substituted naphthalene or estolidene; b) a hydrogenated or fully hydrogenated polyisobutylene or a mixture or hydrogenated or fully hydrogenated polyisobutylene; and c) additives, individually or in combination with each other. In the case of the high-temperature grease, a thickening agent is added.
Abstract:
The present invention relates to the use of a grease (25) comprising a calcium sulfonate thickener for prolonging bearing life of a bearing (5) that is lubricated with the grease, wherein the bearing is mounted in a machine that is subject to cleaning with a solution comprising a detergent and wherein the calcium sulfonate thickener provides the grease with detergent resistance, such that the grease retains lubricating ability when contaminated with the cleaning solution.
Abstract:
The invention relates to a substantially thickener-free lubricating grease that consists of perfluoropolyethers (PFPE) and a small fraction of a pyrogenic silica, and also usual additives.
Abstract:
The invention provides a grease composition capable of smoothly operating the lubricated parts even under wide-ranging temperature conditions, and at the same time, exhibiting excellent noise reducing effect on the lubricated parts. The grease composition containing a base oil and a thickener is provided, wherein the base oil includes at least one first base oil selected from the group consisting of poly-±-olefins and ethylene-±-olefin oligomers and at least one second base oil selected from the group consisting of polybutene, polyisobutylene, polymethacrylate, and styrene based copolymers, with the first base oil being contained in an amount of 65 mass% or more and the second base oil being contained in an amount of 1 mass% or more and less than 35 mass% based on the total mass of the base oil, the base oil having a kinematic viscosity of 350 to 1400 mm 2 /s at 40°C, the first base oil having a kinematic viscosity of 300 to 1200 mm 2 /s at 40°C, and the second base oil having a kinematic viscosity of 1500 to 200,000 mm 2 /s at 40°C.

Abstract:
Methods of lubricating food processing equipment that include applying a food grade, high temperature lubricant composition to the food processing equipment are described. The composition includes a polyol polyester base oil that is a reaction product of at least one neopentyl polyhydric alcohol and at least one monocarboxylic acid. Also described are methods of preparing a food grade, high temperature composition comprising reacting at least one neopentyl polyhydric alcohol and at least one monocarboxylic acid. The composition may be a lubricant composition. Additionally, the invention provides a food grade, high temperature lubricant composition comprising a polyol polyester base oil that is a reaction product of at least one neopentyl polyhydric alcohol and at least one monocarboxylic acid.
