Abstract:
A lubricant for a run-flat tire system includes a solubilized oil, an oil-miscible or oil-soluble carrier fluid or other non aqueous carrier fluid, a thickener, and a surfactant. The thickening system hereof retains its rheological properties and is not subject to permanent thinning shear. When admixed with optionally, a surfactant and, a lubricity agent, the lubricant exhibits long term viscometric stability (shelf life) and prevents the buildup of heat due to friction in the tire assembly when the tire is in the run-flat condition.

A UV-stable lubricating and/or sealing compound, and method for production thereof. The compound includes a base oil and a powder-form inorganic thickener distributed homogeneously therein. At room temperature, the base oil has a vapor pressure of
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:
PURPOSE: A manufacturing method of aqueous slurry suspension and aqueous slurry suspension are provided to offer aqueous slurry suspension which can be used in separation of particle, CMP application, and lapping application. CONSTITUTION: A manufacturing method of aqueous slurry suspension comprises a step of manufacturing suspended particles selected from a group consisting of stable gel particle, sol-gel, and gelatinous precipitates in order to precipitate inert particle in carrier media. The carrier media is different from the inert particle and includes about 0.1-60 weight% of suspended particle selected from oxide which forms the suspended particle in the carrier media having pH of 3-12, hydroxide, and oxide hydroxide. The particle is suspended as a result of one of the following reasons: physical interference, density difference, and static charge.
