Title: (EN) ADDITION-CURABLE SILICONE RUBBER COMPOSITION AND AIRBAG
(ZH) 加成固化型硅橡胶组合物和气囊
Abstract:
(EN) Provided is an addition-curable silicone rubber composition for airbags. An addition-curable silicone rubber composition which contains: 100 parts by mass of (A) an organopolysiloxane that contains two or more alkenyl groups in each molecule; (B) a cyclic organohydrogenpolysiloxane represented by formula (1), wherein the polysiloxane content is 50 mol% or more relative to the total amount of the component (B) when m=2; (C) an organohydrogenpolysiloxane represented by formula (2), which contains two or more silicon atom-bonded hydrogen atoms in each molecule, in such an amount that the number of silicon atom-bonded hydrogen atoms in the components (B) and (C) is 1 to 7 per one silicon atom-bonded alkenyl group in the component (A) and the number of silicon atom-bonded hydrogen atoms in thecomponent (B) is 1-30% of the number of silicon atom-bonded hydrogen atoms in the components (B) and (C); 0.1-50 parts by mass of (D) a fine silica powder having a BET specific surface area of 50 m2/gor more; and an effective amount of (E) an addition reaction catalyst.
