Elastomer components and molded bodies

Abstract

An elastomer composition, etc., wherein the elastomer composition comprises: an aromatic vinyl compound elastomer (A), an oil (Y) with a kinematic viscosity of less than 50 mm² / s at 40°C, and an organic additive (Z) soluble in the aforementioned oil (Y) at 160°C, wherein the amount of the aforementioned oil (Y) relative to 100 parts by mass of the aforementioned aromatic vinyl compound elastomer (A) is in the range of 500 parts by mass to 4000 parts by mass, the content of the aforementioned organic additive (Z) in the aforementioned elastomer composition is 0.5% by mass or more, and satisfies the following requirement: when a solution of 2.34% by mass of the organic additive (Z) using a specific solvent is made at 50°C ± 5°C over a period of 30 minutes, the substantial precipitation amount P is greater than 0.
