Abstract: Provided is a rubber composition containing a high stratified or tabular clay mineral content, wherein the dispersion of the stratified or tabular clay minerals is improved, thus reducing air permeability and improving flex resistance. Also provided is a tire using the rubber composition. An example of the rubber composition is a rubber composition containing a rubber component (A), a stratified or tabular clay mineral (B), and a glycerin fatty acid ester composition (C).

Abstract: The present invention relates to [1] a plasticizer for a halogen-based resin containing a mixture of didecyl phthalates each containing a linear or branched C10 alkyl group, in which a content of di-n-decyl phthalate in the mixture is not less than 48 mol % and not more than 70 mol %; [2] a plasticizer composition for a halogen-based resin containing the aforementioned plasticizer; and [3] a halogen-based resin composition containing a halogen-based resin and the aforementioned plasticizer. The plasticizer of the present invention has an excellent plasticizing effect on a halogen-based resin and at the same time, can exhibit excellent effects of improving all of productivity, processability, kneading properties and heat resistance without deterioration in the respective properties.

Abstract: The present invention relates to [1] a plasticizer for a halogen-based resin including a condensate obtainable by an esterification reaction between a furan dicarboxylic acid compound and an aliphatic alcohol having 4 to 22 carbon atoms, in which the aliphatic alcohol includes a saturated aliphatic alcohol and an unsaturated aliphatic alcohol, and a content of the unsaturated aliphatic alcohol in the aliphatic alcohol is not more than 25% by mass; and [2] a halogen-based resin composition including the aforementioned plasticizer. The plasticizer has a plasticization performance for a halogen-based resin at a level identical to or higher than that of a phthalate-based plasticizer, and exhibits excellent effects of improving compatibility, heat resistance and cold resistance.
