摘要
A silicone rubber-based curable composition of the present invention contains: a vinyl group-containing organopolysiloxane (A); an organohydrogen polysiloxane (B); silica particles (C); a silane coupling agent (D); and a platinum or platinum compound (E), wherein satisfied is the following requirement X, or both the following requirements X and Y: Requirement X: the vinyl group-containing organopolysiloxane (A) contains both a vinyl group-containing linear organopolysiloxane (A1) and a vinyl group-containing branch organopolysiloxane (A2), Requirement Y: the organohydrogen polysiloxane (B) contains a mixture (B3) of a linear organohydrogen polysiloxane (B1) and a branch organohydrogen polysiloxane (B2), or the branch organohydrogen polysiloxane (B2). This makes it possible to provide a silicon rubber-based curable composition which can produce a silicone rubber having excellent tensile strength and tearing strength.
