PROBLEM TO BE SOLVED: To provide a silicone rubber-based curable composition, and to provide a method for producing a silicone rubber-based curable composition, and the like.SOLUTION: A silicone rubber-based curable composition from which silicone rubber exhibiting physical properties comprising a breaking elongation of ≥1,400% and JIS K6252 (2007) notched crescent shape tear strength of ≥40.0 N/mm after cured is obtained. A method for producing a silicone rubber-based curable composition includes a step of kneading a vinyl group-containing organopolysiloxane (A), an organo hydrogen polysiloxane (B), silica particles (C), a silane coupling agent (D), and a catalyst (E), wherein the content of the silica particles (C) in the kneaded product is 36-53 pts.wt. per 100 pts.wt. of the total amount of the vinyl group-containing organopolysiloxane (A) and the organohydrogen polysiloxane (B). |
