Abstract:
A thermally conductive silicone grease composition comprising at least the following components: an organopolysiloxane (A) represented by the following general formula : [wherein R1 designates identical or different univalent hydrocarbon groups; X designates identical or different univalent hydrocarbon groups or alkoxysilyl-containing groups of the following general formula: -R2-SiR1a (OR3)(3-a) (wherein R1 designates the previously mentioned groups; R2 designates oxygen atoms or alkylene groups; R3 designates alkyl groups; and 'a' is an integer ranging from 0 to 2); and 'm' and 'n' are integers equal to or greater than 0, respectively]; a thermally conductive filler (B); and an organopolysiloxane (C) having silicon-bonded hydrogen atoms on both molecular terminals and in the molecular chains; is characterized by excellent resistance to heat and reduced oil bleeding.
Abstract:
A grease composition using lubricating base oil that is biodegradable by microorganisms in nature and has an affinity to the human body is provided. More particularly, a distillation residue secondarily generated in production of biodiesel from vegetable oil (soybean oil and canola oil) is used as the lubricating base oil. The grease composition is produced by adding 1 to 20wt% of additives to 100 to 95wt% of distillation residues, which is generated in production of biodiesel, and 1 to 30wt% of thickeners.
Abstract:
Provided is a grease composition with a long service life under high-temperature conditions, considerable low-evaporability, and incombustibility. The invention provides a grease composition comprising, as a base oil, an ionic liquid formed of a cation and an anion and having an ion concentration of 1 mol/dm 3 or more as measured at 20°C, and a thickener having a dropping point of 260°C or higher.
Abstract:
A grease-like silicone composition comprising at least (A) a liquid organopolysiloxane comprising 80 to 96.5 mol% of siloxane units represented by the formula R2SiO2/2, 1.0 to 10.0 mol% of siloxane units represented by the formula RSiO3/2, and 0.25 to 10.0 mol% of siloxane units represented by the formula R3SiO1/2 (in the formulas, R stands for identical or different monovalent hydrocarbon groups) and (B) a thickening agent is disclosed. A grease-like silicone composition can be provided that is capable of containing a large amount of thickening agents and possesses superior heat resistance.
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:
High-temperature inhibitor materials for use with electrical connections in energy transmission and distribution systems where operating temperatures exceed 150 °C. The high-temperature inhibitor materials comprise base oils and conductive particles, wherein the high-temperature inhibitor is stable at temperatures above 150 °C.
