|1. (WO2018198830) ADDITION-CURABLE SILICONE RUBBER COMPOSITION|
|Applicants:||SHIN-ETSU CHEMICAL CO., LTD.
|Title:||ADDITION-CURABLE SILICONE RUBBER COMPOSITION|
[Problem] The purpose of the present invention is to provide an addition reaction-curable silicone rubber composition which can give a molded article in which oil bleeding properties and mold release properties can be controlled without increasing the added quantity of a bleed oil. [Solution] An addition reaction-curable silicone rubber composition characterized by containing the following components (A) to (D): (A) 100 parts by mass of an organopolysiloxane having at least two silicon atom-bonded alkenyl groups per molecule; (B) 0.2-20 parts by mass of an organohydrogenpolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; (C) a catalytic amount of a platinum group metal catalyst; and (D) 1-10 parts by mass of a silicone oil which is represented by general formula (1), which has a monovalent aromatic hydrocarbon group at a quantity of not less than 35 mol.% and less than 50 mol.% relative to the overall quantity of silicon atom-bonded substituent groups, and which has a specified siloxane chain length.
