Abstract:
Grease composition for use in resin lubrication incorporating into a grease base material which includes a base oil and a thickener at least one saturated or unsaturated fatty acid having from 8 to 22 carbon atoms and/or fatty acid metal salt, being a metal salt of a linear saturated fatty acid having from 8 to 14 carbon atoms or a metal salt of an unsaturated fatty acid having from 16 to 22 carbon atoms and from 1 to 4 unsaturated groups, the metal having a valence of from 1 to 4, wherein the thickener excludes said fatty acid metal salts.
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:
The invention relates to a method of reducing the inhalation toxicity of functional fluids by incorporating into a functional fluid an effective amount of a copolymer which is obtainable by copolymerizing ethylene oxide, propylene oxide and/or butylene oxide with an initiator monool or diol, said copolymer having a degree of unsaturation of less than about 0.01 meq/g.
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 grease composition for use as a cable filling material which contains about 25 to 75 parts by weight of castor oil or a ricinoleate polyol, about 13 to 71 parts by weight of a hydroxy-terminated polymer of polymerized castor oil or the reaction product of a polyisocyanate compound and castor oil or a ricinoleate polyol, and about 4 to 12 parts by weight of colloidal particles such as silica, clay or mixtures thereof. Optionally, an antioxidant component can be added to impart high temperature resistance, a bleed inhibitor, typically of a rubber component, can be added to improve bleed resistance, a water blocking agent of a superabsorbent compound can be added to reduce water transmission, microspheres can be added to reduce the weight of the formulation, and/or conventional additives such as fungicides, bacteriocides etc. can be included. The invention also relates to an article of manufacture such as a cable having a sheath surrounding a plurality of optical fibers therein, with one of the grease compositions of the invention located therein.
Abstract:
The invention provides composites of organic polymeric compositions including a matrix of an organic polymer and a filler distributed throughout the matrix, the filler being present in the matrix substantially as separate particles, each about the fundamental particle size of the filler. The fillers are unique mixed metal hydroxide compositions that are obtainable in sub-micron size particles. These particles are layered and have a BET specific surface area in excess of about 100 m2/g. An anion of the particulates is selected to be compatible with the organic polymer thereby providing ease of dispersion of the filler particles throughout the polymer matrix.
Abstract:
A grease composition for use as a cable filling material which contains about 75 to 95 parts by weight of a base component of a liquid or semi-solid polyol having a molecular weight of at least 4000 and a reduced amount of mono-unsaturated compounds, about 1 to 15 parts by weight of a thickening agent such as colloidal particles of silica, and between 1 and 5 parts by weight of an antioxidant. Optionally, a thermoplastic elastomer can be added to improve bleed resistance.
