Abstract: In the friction material used for the disc brake pad, which is manufactured by forming a non-asbestos-organic (NAO) friction material composition, it is an object of this invention to provide the friction material that satisfies the laws and regulations with respect to the amount of the copper component contained therein and at the same time inhibits the generation of the just-before-stopping noise. In the friction material used for the disc brake pad, which is manufactured by forming a non-asbestos-organic (NAO) friction material composition that contains the binder, the fiber base, the inorganic friction modifier, the organic friction modifier, and the lubricant but does not contain the copper component, the friction material composition contains 0.

Abstract: The present invention addresses the problem of providing a disc brake pad friction material, which is capable of securing fade resistance and wear resistance while satisfying laws relating to copper component content and for which coating by electrostatic powder coating is favorable. As a means for solving the problem, a friction agent composition, which contains 0.3-5 weight % of flake graphite particles of 1-100 ?m mean particle diameter with respect to the total amount of the friction material composition as a lubricant and in which the total amount of copper components contained in the friction material composition is less than 5 weight % of the total amount of the friction material composition, is used. Preferably, the flake graphite particles are aggregates. It is also preferable that the friction material composition contains mica with a mean particle diameter of 100-400 ?m.

Abstract: In relation to the NAO friction material free of copper component, this invention is to provide the friction material that prevents the occurrence of metal catch while securing sufficient wear resistance. In the friction material manufactured by forming the NAO friction material composition free of copper component, the above-described friction material composition contains no metal simple substance or alloy other than copper and contains, as the lubricant, metal sulfide having 600 centigrade or higher decomposition temperature to be decomposed into metal and sulfur. Especially, the above-described metal sulfide is preferably zinc sulfide, and the content thereof is preferably 0.5-2.0 weight % relative to the total amount of the friction material composition. Also, as the lubricant, the friction material further contains 2.0-5.0 weight % of graphite relative to the total amount of the friction material composition.

Abstract: The detergent composition of this invention, which is suitable for fuel-system parts, contains a saturated or unsaturated fatty acid containing 18 carbon atoms, a mixture of ammonia and amine an ester of a higher fatty acid, and water. It is also possible to add an antioxidant and a metal-deactivating agent. When mixing the above components, it is also possible to use a diluent and a solubilizing auxiliary solvent in order to impart suitable degrees of viscosity, fluidity and phase-solubility.Therefore, it is capable of removing foreign matter stuck on the fuel-system parts in a shorter period of time and gives less deleterious effects not only to fuel but also to various materials used to make up the fuel-system parts.
