Abstract: An oleaginous composition is solidified at ambient temperature and in divided form, includes an oil, including at least one hydrocarbon oil of petroleum origin, and at least one chemical organogelator additive. The composition is used as a plasticiser, in particular in tyre production, or as a solvent, in particular in ink production. A method transports and/or stores and/or handles oleaginous compositions that are solid at ambient temperature and in divided form.
Abstract: The present invention provides a rubber composition obtained by kneading a rubber component, a vulcanization accelerator, silica, and a compound represented by the following formula (I): wherein the groups are as defined in the DESCRIPTION.
Abstract: Provided is a rubber composition including: per 100 parts by mass of a diene rubber containing a natural rubber and from 10 to 30 mass % of a butadiene rubber, from 50 to 100 parts by mass of a filler containing not less than 20 mass % of carbon black, oil, sulfur (S), and a vulcanization accelerator (A), a mass ratio of the natural rubber to the butadiene rubber (NR/BR) being 0.3 or greater, a compounded ratio of the sulfur to the vulcanization accelerator (S/A) being 0.8 or less, and a total amount of an oil component in the rubber composition containing the oil being from 15 to 25 parts by mass.
Abstract: A rubber composition for a tire according to an embodiment of the present technology includes: 100 parts by mass of a diene rubber and from 1 to 30 parts by mass of a thermally expandable microcapsule composite body, and the thermally expandable microcapsule composite body contains one or more thermally expandable microcapsules and an acrylonitrile butadiene copolymer and/or a crosslinked body thereof covering the one or more thermally expandable microcapsules.
