Abstract:
A heat dissipating silicone grease composition is provided to easily and uniformly coat, to improve a preserving stability at a room temperature, to facilitate the handling and to realize charateristics of heating and disssipation. A heat dissipating silicone grease composition comprises (A) an organopolysiloxane 0 - 30 mass % in which the dynamic viscosity indicated as below chemical formula 1 of 25 deg.C is 50 - 500,000 mm^2 / s; (B) an organopolysiloxane 0 -30 mass % indicated as the following chemical formula 2, wherein the sum of (A) and (B) is 3 -30 mass %; (C) a thermally conductive filler 60 - 96.9 mass % having a thermal conductivity more than 10 W / m deg.C; and (D) a non-volatile isoparaffin compound 0.1 - 10 mass % which can disperse and dissolve the (A) and (B) and has a boiling point 260 - 360 deg.C, wherein the sum of (A) and (D) is 100 mass %.
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 grease composition comprising a grease containing, in a base oil thereof, from 2 to 40% by weight, based on the total composition, of tricalcium phosphate [Ca3(PO4)2], the grease further containing (A) from 0.5 to 10% by weight, based on the total composition, of a molybdenum dialkyldithiocarbamate sulfide and (B) from 0.1 to 5% by weight, based on the total composition, of at least one of a zinc dialkyldithiophosphate and triphenyl phosphorothionate. The grease composition is excellent in mechanical stability, heat resistance, extreme pressure properties, and wear resistance.
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 lubricant having good extreme pressure properties and wear resistance contains not less thatn 0.1% by weight of at least one metallic phosphorus chalcogenide or an intercalation compound thereof.
Abstract:
High dropping-point lithium-complex grease composition having improved extreme pressure properties, comprising a lubricating oil and the following components: (a) at least one lithium soap a C12 to C24 hydroxy fatty acid, (b) at least one lithium salt of a boric acid, and (c) at least one metal salt selected from the group consisting of 1) a potassium salt of a boric acid, 2) a sodium salt of a boric acid, 3) an alkaline earth metal salt of a boric acid, and 4) a zinc salt of a boric acid.
