Document Type and Number:
WIPO Patent Application WO/2017/217088
Kind Code:
A1
Abstract:
Provided is an addition-curable liquid silicone rubber composition which has good curability and still provides a silicone rubber having a durometer type A hardness of 5-15 as measured after being cured and a high tear strength. The addition-curable liquid silicone rubber composition contains (A) an alkenyl group-containing organopolysiloxane having two or more silicon atom-bonded alkenyl groups per molecule, and an average polymerization degree of 1,500 or less, and is liquid at 25°C, (B) (B-1) an organohydrogenpolysiloxane containing six or more silicon atom-bonded hydrogen atoms per molecule, and not having an aromatic group, (B-2) an organohydrogenpolysiloxane containing 3-5 silicon atom-bonded hydrogen atoms per molecule, and not having an aromatic group, (B-3) an organohydrogenpolysiloxane containing 1 or 2 silicon atom-bonded hydrogen atoms per molecule, and not having an aromatic group, (C) a fumed silica having a BET specific surface area of 130 m2/g or more, and (D) an addition reaction catalyst.
